What I have found is there is a tiny minority of people who _hate_ bikers. They tend to pop up and make wild claims about how dangerous bikers are, or how much they dislike how bikers use the streets since streets are for cars, and bikes are for children. What I have found in actually talking to people is most people support and encourage bikes, and would love to bike, but don't feel safe. Bikes make everything about traffic better, and most bikers observe the traffic laws. The best response to people who protest is to continue biking just like you would normally. As bike use grows everyone is safer, and more people feel safe biking. That grows the bike community and helps make a safer place for biking for everyone

As a pedestrian in a dense Californian urban core, I have mixed feelings about bikers.

Most bikers are reasonable, sensible bicycle commuters. They stay in the road, wear helmets, and follow laws. No skin off my nose. (ecologically friendly, fights obesity, blah blah blah blah blah)

But I've also had multiple encounters with bicyclists who feel they are entitled to switch back and forth between a wheeled vehicle moving significantly above normal walking speeds and a pedestrian who just happens to be on a bicycle. Usually with no notice and as is convenient for them. Not infrequently such enhanced-pedestrians can top 20 mph barreling down the sidewalk. Sometimes with cargo in tow. I have literally never even heard of there being any real consequences for such irresponsible and reckless behavior.

I understand why they do it. It's so convenient! Roads certainly aren't always designed for the safety of bicyclists. Yet, these are perhaps less than adequate reasons for irresponsible behavior.

More troubling to me is the role bicycles seem to play in the underground economy of the Bay. But that seems more an issue stemming from law enforcement's general disinclination to be interested in bikes and bikers at all.

because they can. trying to pigeonhole cyclists as either cars or pedestrians is exactly why so many confrontations occur. its not that a cyclists prefer sidewalks as they are horrible to bike on (bumpy, uneven, inconsistent, obstacled), its that on some roads a distracted driver can mean near certain death. Its not irresponsible, its moving a 20 pound object around 100-200 lb people (if pedestrians cant be avoided) instead of holding their own against 3 ton cages.

Are there douchey cyclists? yes. But just try getting down one block of SF only in the bike lane. You’ll be stuck behind a ups truck or broken muni for days or pop a tire on a broken bottle some hobo left there or get hit in the face with a door.

Moving a 20-pound chunk of metal at 20 mph with a 100-200 squishy on top amidst a bunch of unsuspecting and unexpecting other squishies may be less than maximally safe for all squishies involved. We're talking about 40-some-odd times more kinetic energy than your average squishy walking at 3 mph.

If you're forced to move into pedestrian space for safety from giant metal cages, the safest option is to actually become a pedestrian. For you and for the other squishies around. I understand that it's slow, uncomfortable, and an unpleasant cycling experience. I appreciate the sacrifice you make for the safety of your fellow squishies.

I'd also be happier with Bay biking culture if it didn't consistently make excuses for douchey cyclists.

Yes, or at the very least, slow down to a reasonable speed instead of weaving in and out among the pedestrians. It's incredibly disorienting to have someone fly right by you at 20mph with zero warning. Scares the hell out of me every time.

If they are riding 20mph on the sidewalk, THAT'S the problem. At a more appropriate speed, it's safer for everyone.

In SF you're legally not allowed to ride on sidewalks if you're over age of 13.

seems like a bad law. i won’t ask anyone to risk their lives over a bad law

you're also allowed use of full lane

Mostly issue with city biking is drivers who think that roads are strictly for cars

Seems perfectly reasonable to me. Biking on the sidewalk is not safe.

you can't possibly know that for a vast amount of situations right?

Certainly it depends on the road, but the most common type of accidents are cars failing to yield while turning, either into other roads or driveways.

Cars are looking for road traffic when they’re turning, so to be most visible you should be on the road. They’re not looking for cyclist riding 15-20 mph on the sidewalk.

And in my experience, all of the close calls I’ve had have been while riding on the sidewalk. The closest I ever came to getting hit was a car turning while I was crossing a crosswalk at speed. I had to swerve and jump the curb to avoid getting hit.

Also, cars and cyclists are much more similar than pedestrians and cyclists are. Pedestrians can stop and turn instantly, while cars and cyclists cannot. Pedestrians also are likely to be on their phone, walking a dog, or pushing a stroller. Or all of those at once.

I enjoy cycling as much as anyone, but I detest a fairly sizable portion of cyclists I encounter throughout the city. In my part of the city it's assumed by most drivers that if a cyclist is riding through the neighborhood that they will completely disregard the stop sign and act accordingly. It can be confusing to them when a cyclist observers right-of-way.

I'm no saint, I practice the Idaho Stop too but if I'm at a four-way stop and two cars stop before me, then of course they get to go.

> I'm no saint, I practice the Idaho Stop too

There are two parts to complying with a stop sign:

1. Come to full stop

2. Yield to any traffic that has the right-of-way before proceeding

The problem with a lot of stop sign installations in the US is that they're largely unnecessary since it's possible to yield to traffic that has the right of way without having to come to a full stop first (since there's plenty of visibility of approaching cross traffic). That's why cyclists do "Idaho stops" and car drivers do rolling stops.

If authorities would only post traffic control devices in areas that are absolutely necessary, instead of having a blanket rule for using them, then compliance would go up substantially and complaints about cyclists and cars running stop signs, for example, would be next to non-existent.

> can top 20 mph barreling down the sidewalk. Sometimes with cargo in tow.

I would be very surprised to see that on a side walk. 20mph is above the speed limits for cars in cities here in Sweden, and I recall reading that while the police can catch people speeding on bikes that its not very likely event.

> Usually with no notice and as is convenient for them

Seems similar to parents with strollers. I have never heard of a parent being confronted by police for reckless engagement of children when walking on the bike road, and it is almost as if people do not view it as reckless. I am pretty sure through that people would react if a parent started to walk with the stroller onto the road against car traffic.

I would be very interested to know how many people would confront a stranger that is walking a stroller on a bike road, or even just quietly consider it reckless.

> I would be very surprised to see that on a side walk

I don't walk to work with a radar gun, but sidewalk-bikes barreling down on me are a daily occurrence (San Francisco). Not people coasting down the block, people actively pumping and dodging. I've been run over by a bike twice, and while I'll take that any day vs. a car, those shitheads need to stay off the sidewalk.

I am very pro-bike. I road one to work daily, until a couple of scary incidents put me off it. I no longer ride much[1].

That said, the jerks on the sidewalk, along with some of the more aggressive bikers, really need to be locked in a room with the entitled auto-rageoholics. The survivors can enjoy the nicer streets with the rest of us after they graduate from the reeducation camps.

[1] Had a couple bad incidents nearly back-to-back, and am probably doing that thing where one's risk aversion increases with age, but I don't feel safe riding anymore.

Is that down a big hill? Naturally local phenomenon can be at any part of a variance, but it seems very odd. Even on a large stretch of leveled road, few bikes get close to 15 mph and the only time I have seen one go faster is from a professional biker, on a racing bicycle, doing a training run, and I would assume that their training paths don't generally include cargo and sidewalks.

The average bike speed, as far as I know, is average 10 mph on city bike roads. Seeing a bike going 20 on a city sidewalk is like seeing a car going 150 on narrow city roads. I am sure it happens, but it is illegal, very dangerous, and not something most people will ever see in a life time. I think it is just fair to treat both forms equal and address it for what it is.

San Francisco has a number of large hills and other slopes where natural local phenomena can significantly enhance velocity.

Places with many large hills don’t tend to get many bikers.

You may find that San Francisco is an unusual place in a number of ways.

In which case we shouldn’t be using it as an example to argue about what should be done in the general case, e.g. nationwide.

Years ago in Oslo the police and the national broadcaster (NRK) set up and experiment where they would radar the bikers coming down a small bike road incline.

The fastest they clocked were nearly 80kmh. If you go that fast on motorcycle you are expected to wear a massive helmet and suit, yet the person likely did it wearing spandex and a bike helmet (if that).

now that speed was highly unlikely to be maintained, but do not underestimate the kinds of speeds a bicycle can get up to under the proper circumstances.

> Bikes make everything about traffic better, and most bikers observe the traffic laws.

Anecdata time.

Practically every single day I'll see bikes casually going through red lights, usually moving between pedestrians crossing. Now, I'll freely grant that they're usually paying enough attention to be safe - but you can bet motorbikes (and even cars) could make those very same judgement calls - except they'd get done by cameras/police.

Bikes are not obviously safer than a car to me as a pedestrian. They're less predictable, less regulated, and typically less careful of pedestrians. Heck, they also probably travel faster than cars most of the time in central london since the speed limit is 20mph everywhere on the rare occasion there's no traffic.

Then of course there's the idiots riding along on the pavement because they can't easily filter through traffic and why should they have to wait in line to move on etc etc.

I'm actually pretty solidly pro properly segregated bike lanes, but if I had to rate drivers vs cyclists in a "most likely to have a collision with as a pedestrian" I would easily go with the cyclist.

They are obviously safer though, as evidenced by the differing rates of pedestrians injured by cyclists vs cars drivers.

> but if I had to rate drivers vs cyclists in a "most likely to have a collision with as a pedestrian" I would easily go with the cyclist.

I don't want to start an argument, but I bet we could look up driver -> pedestrian accidents, and see how many were reported vs cyclists -> pedestrian accidents.

Personally, I would much rather get hit by a cyclist as a pedestrian, than a car, and that's simply physics. I've been hit as a pedestrian multiple times by cars (thankfully, at low speed), but never by a bike. I've been hit by a car while riding a bike.

You do not want to get hit by a car, while riding a bike. The car always wins. Thankfully, I survived.

>> if I had to rate drivers vs cyclists in a "most likely to have a collision with as a pedestrian" I would easily go with the cyclist.

I'd weight it by, well, mass and associated likelihood of actual harm, personally.

I'm a fairly keen (but casual) cyclist. I wouldn't cyclce in London by preference, and I have seen some terrible behaviour by cyclists in London.

One day at 9am in the City, I saw a cyclist swearing loudly at everyone and pushing through the crush as people tried to cross Liverpool Street, at a pedestrian crossing, when the lights were red for traffic.

Total arsehole. I thought to myself "this is why people think cyclists are all bastards, people like you".

> I'm actually pretty solidly pro properly segregated bike lanes, but if I had to rate drivers vs cyclists in a "most likely to have a collision with as a pedestrian" I would easily go with the cyclist.

Possibly, but if you'd pick a more reasonable metric, such as accidents that actually result in serious injury, cars are apparently ahead, by a 6000% margin; http://road.cc/content/news/109269-are-drivers-and-cyclists-...

>most bikers observe the traffic laws

Not in Philadelphia, at least. I walk everywhere, and racking my brain for bike encounters I can only recall one of maybe 20 instances in which a bike actually stopped at a red light. I can recall at least a third of those instances where bikes were travelling the wrong way on a one way street, and another third with bikes on the sidewalk.

That being said, I still think biking is a net positive. It would be better if the roads were designed with bikes in mind. The problem with bad human behavior is almost never the human, but the system that's designed to disincentivize the good behavior.

I obey traffic laws when it is safe to do so. There are some dangerous interections around here where the bike lane disappears then starts up again. If you ride with the traffic as you're supposed to, cars behind will try to pass in the middle of the intersection. In those cases, sometimes I will ride up on the sidewalk to bypass the dangerous part of the itnersection. I would feel better if there was a separate light in the bike lane that allowed the bikes to proceed first.

This is the correct answer.

One of my safety heuristics is "clear the intersection". Sometimes that means jump the light, or follow a car thru a 4-way, or full stop (foot on ground) to clearly signal I'm waiting my turn.

I obey stoplights on my bike, but it's really punishing sometimes. Bikes don't trip the sensors so the light will ignore you until a car pulls up behind you. This can require three or four cycles of the lights if traffic in your direction is sparse.

I've heard that if you get off and lay the bike on its side, it can help trip the sensor. Usually they're electromagnetic, so on its side the bike is a good inductor, but not in its normal position.

I'll give this a try. It should be pretty obvious if it works.

They sell magnets for motorcycles that are supposed to help trip the light sensor. Might be worth checking out?

In the UK at least, you can often see a rubber strip in a square where the sensor has been added to the road (they cut a slot then re-seal it). I try to stop with my wheel rims right on strip and it often triggers the lights. In fact, I wonder sometimes if it actually senses stronger because the metal wheel rim is so much closer as I've had the light turn immediately if I get it just so. (the specific junction I use is only detector triggered, it doesn't time back and forth at all)

Sadly, the roads around here don't have visible seams where the sensors are. I'm going to have to guess.

I mean, this is a very good example for the kind of care taken by the people designing and overseeing roads in respect to cycling.

Can you fucking imagine shipping a product that just plain doesn't work for a large part of what the law defines as a vehicle? For something as crucial as a light? Can you imagine installing that as the government, not in some test locations, but all over?

I'm not quite sure what specifications lights need to conform to but a good fricking starting point seems like the law. These things are just plain defective.

I am from philadelphia as well so I know there are bikes who stop at red lights and stay on the streets. I am not so nieve to think everyone does as I have also run across people who don't obey any traffic laws, but over the last 15 years biking in philly has grown up a lot, and people who used to rationalize their behavior because of lack of infrastructure are changing their ways and coming in line with what is expected of bikers in an urban setting. There will always be those who don't follow the rules, just like there are pedestrians and cars who don't follow the rules, but the situation in that city has gotten so much better, not because new laws were passed or cops cracked down on people running stop signs. The situation got better because more people bike, we put up bike lanes, and drivers got used to bikes being in the street with them.

As a biker in Philly - I'll start following the rules of the road when the cars do. I've lived in other cities where I obeyed every traffic law, just like I was in a car. If you do that in Philly, you get run over by a car or hit a jay walking pedestrian.

This attitude is exactly why some people hate bikers. It's not productive, if everyone takes this attitude then nothing is going to get better. Step up and be a model for the behavior you want to see around you.

I'd rather not die.

Don't be so dramatic. Waiting at red lights isn't going to kill you, in fact it may do the opposite.

I do stop at red lights or at least slow down and make sure the way it is safe to cross, that isn't the problem. I just have to constantly jump up onto sidewalks. After stopping at the light - especially if there are cars trying to take a right and the way is clear - I will go before it turns green. I rarely stop at stop signs for four way stops.

In general, traffic isn't paying attention. They will swerve blindly into the bike lane to get around other cars to take a right and I can't depend on them to be watching out for me.

Once I stop moving I remove the option of swerving out of the way. After my first month of biking here and almost getting hit several times, I just gave up and I ride as aggressively as everyone here drives. I hate it. Biking in New York, Portland or anywhere else I've lived is just a different game. Philly is the most stressful place I've biked.

Just an FYI in many states, cities, etc. It's legal to move to the bike lane for a right lane. That's why it's often a dotted white line.

Not saying that's safe... But it is legally accepted

It is legally accepted, after checking to see if the lane is clear.

Waiting at red lights _can_ be more dangerous than not waiting. Ask motorcyclists how they feel about being the lone vehicle at a redlight.

Are you going to elaborate on that, or should I conjure up a motorcyclist from thin air and ask them how they feel?

If that's a riddle to you, you are the danger

Come on, I don't even drive. Get out of here with your pretentious angle, none of this helps your cause.

It can be dangerous to be the only person or vehicle at a red light if you are a motorcyclist or bicyclist because cars can fail to notice you until they are quite close. Many motorcyclists apply and release their brakes, and sometimes add modifications to their tail lights so that they flicker when coming on to make it even more noticeable.

I pay at least as much attention when I am the lone cyclist at a red light (particularly at night) as when I am actively moving and riding in traffic, and have had a number of vehicles come to a stop a bit close or a bit too quickly for comfort. This is in an area with _a_lot_ of cyclists.

Thanks for elaborating. It sounds to me though that the solution is modifying your tail lights to be more apparent, rather than running all the red lights.

I will also concede that motorcyclists are generally much better on the road than "analog" bikes, at least when they aren't in a group and their loud-ass bikes aren't waking me up at 1 AM.

> It sounds to me though that the solution is modifying your tail lights to be more apparent

My tail lights on my bike are rather bright and flashy. It's still happened before. There isn't really "a" solution. It's better awareness, better visibility, everyone being more proactive, etc.

> > most bikers observe the traffic laws

> Not in Philadelphia, at least.

This is mostly solvable by building better infrastructure. Just visit Netherlands or Denmark to see how well things could be organized.

When the infrastructure is bad, bikers (or people in general) will resort to odd behavior just to get by.

I cycle myself and also enjoy the pedestrian life.

Some bikers in the city are irresponsible and ignore traffic laws. The same treatment given to cyclists by some drivers is meted out to pedestrians by some cyclists. Something to do, no doubt, with that pesky issue of power imbalance.

In terms of risk assessment as a pedestrian in NYC, I always watch out for (1) MTA bus drivers, (2) any sort of livery, and (3) people on bikes, in that order.

Uber drivers are working their way up the list for me

"Any sort of livery" would include Uber drivers too, right?

> Bikes make everything about traffic better, and most bikers observe the traffic laws.

In California, bikes seemed alright enough. Lane splitting is legal, most use bike lanes, etc.

That being said, bikes are supposed to act like a vehicle on the road. I.e. stop at stop signs, and go through the stop signs one at a time. Not once have I ever seen this happen. There's also stopping at lights, which happens usually, but typically they then try to act like pedestrians...

Now outside of California, lane splitting is very rarely legal, especially in the Midwest, South, and East. Which means a bike literally has to act 100% like a car, or motorcycle. They can't ride next to a car or pass a car (or line of cars), without moving to another lane. The only exception, is typically if there is a bike lane.

So no, most bikes don't follow the laws. The "minority" of poeple who make "wild claims" are the people who have to drive next to them.

For the record, I've had 5 bikers hit my car (one got a ticket), at least 2 bikers try to squize by and scratch my car, and 1 idiot try to pass me on the right while I made a right turn. That person got pissed, but cop agreed I was in the right. I've lived in Alameda and drove to SF and Oakland regularly, but half of this happened in Champaign IL (on a college campus, where the bikers don't know how to ride or the laws).

In regards to pedestrians, twice I've been hit by a bike where both of us fell down and we were at least shaken. My wife, while in college, was straight up laid out when crossing the street once. The biker needed to be hospitalized, and she was injured (urgent care worked).

Point being, i don't think my opinion are wild. Bikers need education, and currently, riding a bike (especially inappropriately) in many places is dangerous for everyone. I agree that bikes can be more effective. However, in practice I think people should get a biking license. Just a 2 hour class, and a simple test. Know the rules, before you kill yourself or hurt others.

I don't want to negate your personal experiences, since they sound pretty horrific, but from a data perspective, I can't find a single person who was killed by a cyclist in California since 2014. They might be there, but considering the amount of coverage I am finding of the crash in 2014 and another in 2012 I am led to believe they don't happen that often. In 2015 alone San Francisco reports 24 deaths due to cars. So while you personally might have had some bad experiences, the majority of bikers are following the rules and people are safer as a result of them biking.

I would be a huge fan of collecting additional data as I am a firm believer that we would see trend lines down where we invest in infrastructure and where biking become more popular.

I agree with your idea that bicyclists need to be educated. As a non-car driver, I remember the first time I went riding in the city with my wife she was shocked that I didn't know how to make a legal left turn. But how was I supposed to know? It is not like the logic behind left turn rules is obvious.

I love biking and I'm a cyclist myself. But I once lived in a small mountain town where it seemed like a big percentage of the cyclists there had an attitude of entitlement about how they cycled. I've never had so many unsafe encounters with bikes, and at slow speeds too (speed limit was 25mph). I think the point I'm trying to make is that there are probably cultural differences between locations and the people who hate bikers have probably had some awful encounters in the past.

I still love cycling and I think it's the best way to get around. It sucks because my city is extremely bike-unfriendly and I don't feel safe biking here.

Crappy humans are crappy, no matter the mode of transport they use.

As a pedestrian I would have a lot more sympathy for cyclists if they stopped at red lights like cars do.

Crossing the street in NYC is more dangerous than it has to be because you always have to be wary of a person on a bike coming out from behind a truck or something.

I don't think the data supports your assertion. Car drivers injure and kill a couple orders of magnitude more pedestrians in NYC than cyclists do.

You're unlikely to report every time a bike runs into you. Most of the time you won't even be really injured - just some bruises and pain. That's not big enough for statistics, but it still sucks as an experience.

My guess is that's the same for cars (minor injuries go unreported). It's hard to speculate about unreported statistics. The fact remains that for reported statistics, motorists injure far more people than cyclists, thus I say fear of cyclists is irrational.

What I have found is there is a tiny minority of people who _hate_ bikers.

I walk 4 miles a day on city sidewalks. The number of times I have to yield to bikers on the sidewalk is disgusting[0]. And some of these bikers are going fast. I once saved a child that was about to run out of a store. I could see, from my vantage point, the biker and the child set for a collision course. I stepped in front of the biker, doing about 20 mph on the sidewalk, to stop them. I got an earful of 4-letter words not a thank you.

Of course, there was the 20-something woman killed in a crosswalk by a biker running a light in SF a few years ago.

As a pedestrian, I have no love for many drivers or bikers, since they are a constant source of danger.

EDIT:

[0] I had an argument with a young woman at a light once, where I told her politely that she wasn't supposed to be on the sidewalk. He response? To tell me I was a selfish person not wanting to share the sidewalk.

Where do you live? I'm in Manhattan, and people rarely cycle on the sidewalk here. There's simply no room to do so, as there's so many pedestrians. You end up going more slowly than if you stayed on the street where you belong in nearly all circumstances.

Don't be too mad at the cyclists, though. Usually they're doing it because the city isn't providing the proper level of bike infrastructure. With more high quality bike lanes that people feel safe using, you'll see a lot fewer cyclists on sidewalks. It works in Manhattan.

> Where do you live? I'm in Manhattan, and people rarely cycle on the sidewalk here.

NYPD ticket like crazy for sidewalk biking. Bay Area cops in the cities don’t really ticket for ‘quality of life’ crimes (or even blatant things like busting out car windows and such).

My understanding is that NYPD stopped going after frivolous violations after the Eric Garner incident a few years ago. I myself was ticketed ($40) once for wearing headphones on both ears, but I haven't seen cops enforcing such rules recently.

I'm a longtime NYer who recently moved to SF. for the past 10 years I've commuted by running each way, ~3-5 miles each way. plenty of experience with bikes and cars in urban areas.

Biking on the sidewalk is WAY more common in SF than in NYC, especially in manhattan. In SF, there seems to be a few main reasons:

1 - Biking on the street would clearly be unsafe. An example here is 3rd st between portrero and soma.

2 - Biking on the sidewalk on the block where you are stopping. These are people that usually bike on the street, but pull onto the sidewalk when they are leaving/entering a building. I understand this, but wish it wasn't so common.

3 - ignorance of, or just not caring about, biking rules and conventions.

It's easy to assume that #3 is always the case and get angry about it, but it's frequently #1 or #2 and I do think some empathy is called for.

I'm curious to hear more about your commute. I live ~3 miles from work, and would love to run there, but there isn't a good way for me to store my towel, a change of clothing, etc at work, and it doesn't seem feasible to carry all of this in a backpack. We do have showers, but they don't have overnight storage.

Sure. The basic answer is that I use a good running backpack and it's easy for me to carry all that stuff. When I first started, I was sparring (boxing) in the morning before work, so I used a eagle creek overnight hiking pack. it was bulky but not too bad for a 3 mile run.

Once I stopped sparring in the morning, I switched to a Black Diamond Dart. Easy to run with, and ample room for all the stuff you mentioned.

I now use a super light pack, and only pack my lunch, pants/shirt/socks/underwear. I live in SF, and generally don't shower unless I get really sweaty. Some people find this gross in theory but I don't, people in NYC get sweaty as hell walking from the subway to work in the summer in their regular clothes, so I've never really seen the difference.

Two big things I do come to mind: I never take my laptop to/from work everyday. I also keep dress shoes at work under my desk.

> I'm a longtime NYer who recently moved to SF.

on HN is there seriously only two places to live in the US?

I don't know about HN, but, I moved to NYC after college because I'm a jazz musician, and NYC is that jazz capital of the world. I've also always worked a day job as a software engineer.

moved to SF last year for work.

Both NYC and SF have a relatively high concentration of tech folks, which is probably a lot of the HN readership.

I do #2 every day because my apartment building doesn't have a curb cut anywhere near its front entrance. Simple fixes like this would improve lives not just for cyclists but also for the handicapped.

When I'm on the sidewalk, however, I'm only going at a brisk walking pace when pedestrians are present.

Im surprised to hear about bike and pedestrian collision in a city. I bike each day and commonly see on bike roads everything from strollers, wheelchairs, to kids who has only barely learned to walk. Each of those would be a fatal if they had a collision with a 20mph biker, and yet not a single death have been reported in my city as far as I know. Its a bit strange, given the number of potential times that this situation occur, especially during winter half year when the road should be extra dangerous.

So I must ask, how much of a freak accident is a traffic death caused by a biker crashing into a pedestrian? I recall looking into statistics for it a while back, but it seems that only data I could find was death caused by people falling down from bikes or into cars, not crashing into other people. The national statistics here in Sweden over road accident, the one which famously has a zero death goal, do include bikes and car collision (3 people died last year) but has no data at all over deaths caused by bike hitting people. Assuming that number is 0.

Is it possible that the 20-something woman killed was a freak accident? 20mph is about 50% faster than the legal limit of a electric bike, would be classified as a illegal moped at those speed if it has a engine, and it is even above the legal limit for cars inside Swedish cities. A bit unusual to see in city traffic.

Why would you think a 20 mph collision with a bike is likely to be fatal? Even a car ped collision at 20 mph is quite survivable; that's why mostly evidence governed countries like Sweden have 20 mph limits, as you get faster you may save time linearly (doubtful in a city, your average is way down there) but chance of survival diminishes by the square.

That said, it happens, but only on the order of 1 or 2 deaths, and in some years none at all. The incidence is extremely low so no meaningful statistics. And then of course it mostly involves an old population who are susceptible to dieing from even a simple fall after stumbling on a tree root. It tells us more about the elderly than risk of cycle collisions.

Better bike infrastructure keeps bikes off the sidewalk.

As a biker you can't win. Drivers try to run you off the road, pedestrians don't want you on the sidewalk. Bike lanes are a solution, but the political will needs to be there.

That being said, in places where bikers feel they have to use the sidewalk, they should absolutely yield to pedestrians.

In places where bikers feel they have to use the sidewalk, they should absolutely walk their bikes. It's what the law says and its very sensible all around. If you have to go the wrong way up a one-way street or if the road is blocked, you can just get off your bike and walk it for a block. It's not the end of the world to have to walk for a minute.

As both a biker and a pedestrian in NYC, this seems so glaringly obvious that it never fails to make me angry when I see a biker blithely biking down the sidewalk. In a city of impatient people riding your bike on the sidewalk is taking things to an anti-social extreme.

That said, I do find it frustrating (as both a biker and a pedestrian) when pedestrians fail to yield to bikers when the biker has the light -- New York pedestrians are opportunistic jaywalkers by nature, but so many people fail to look for bikes or yield to them, even when they have the light, if the street is clear of car traffic.

> they should absolutely walk their bikes.

In many places of the US you have sidewalks built because they were mandated by law but are rarely used.

A typical example will have a 4-lane 45+mph road next to big box retail stores. This type of road is unpleasant to bike on but the adjoining sidewalk is empty and, assuming it has sufficient visibility to allow the cyclist to avoid left and right hooks, is much safer than the road.

NYC is a fascinating and important place but for better or worse is very different from the typical US city.

> It's what the law says

The law varies city by city. Where I live bikes are prohibited from the sidewalk only in the downtown area and it's legal elsewhere. Not that it stops anyone from biking on the sidewalk even downtown or that it ever gets enforced.

pedestrians don't want you on the sidewalk

It is illegal to ride a bike on the sidewalk in every city I know of.

Pedestrians don't have lanes. Pedestrians don't have rules. They might turn suddenly to get into a car, or pop out of a shop. It is just selfish of bikers to think they should be on the sidewalk. It's very dangerous for us pedestrians. In the last 20 years, I've been hit twice on the sidewalk and had to jump out of the way, to avoid serious injury, many times.

> It is illegal to ride a bike on the sidewalk in every city I know of.

While I agree that riding on the sidewalk is generally a bad idea, it's definitely not illegal in all places. For example, in Austin it's explicitly legal except in these locations [0].

> As a biker you can't win. Drivers try to run you off the road, pedestrians don't want you on the sidewalk

you're right, but the attitude that arises from that problem is what most people don't like about city bikers

A woman killed a few years ago by a bike? That's terrible.

Not quite as terrible as one pedestrian being killed every 1.6 hours by cars though. (2015 figures for the USA)

Nice change of subject. I never said cars aren't dangerous to pedestrians.

When I am a pedestrian I would much rather take my chances with a inconsiderate biker than a inconsiderate car driver.

Bikers killing someone are extremely rare. Bikers getting killed by drivers is more common (citation needed).

When I am biking I'd much rather be riding slowly on a sidewalk than getting killed by a inconsiderate driver.

Where I live it is legal to ride on sidewalks in streets with no bike lines. So instead of taking my chances on a busy street I'd much rather ride slowly(10-15 km/h) on a sidewalk.

In an ideal world the cities would have specific bike only lines which cover all areas. I hear Copenhagen and Amsterdam are good with this.

When I am a pedestrian I would much rather take my chances with a inconsiderate biker than a inconsiderate car driver.

It's not a choice. Every pedestrian must deal with both.

When I am biking I'd much rather be riding slowly on a sidewalk than getting killed by a inconsiderate driver.

Here's the thing: the amount of risk you are comfortable with is probably different than it is for me. What bikers who ride on the sidewalk are doing is forcing their risk tolerance on me. Given where I walk it is illegal to ride on the sidewalk, I feel a certain amount of righteousness in asking bikers to get off the sidewalk.

> most bikers observe the traffic laws

Funny, this is the exact opposite view from mine. Just last week I was hit by a bike crossing a street with a walk sign. Those assholes wouldn’t stop for you if you paid them.

Citations? Forget about it. The streets will just get too dangerous for peds and cars.

The majority of bikers I know freely admit, and even take pride in, blowing through stop signs and red lights. “You’re not supposed to stop!”

So you had a run-in with an idiot biker last week. If you live in a busy city, that sounds like a pretty good statistic and you probably have been in several dangerous traffic situations with drivers in that same timespan. This strongly feels like confirmation bias to me.

> most bikers observe the traffic laws

Why the fixation with traffic laws whenever bikes come up?

I bike to work and I don't follow the rules, I run reds, blow stop signs, ride on the sidewalks and so on.

However, I am courteous and polite to everyone. My goal is to not startle or inconvenience any other user of the road (or sidewalk).

Why should I stop at stop signs like a boyscout? That's just false piety.

The rules don't keep us safe, because the rules weren't designed in a perfect world.

What would help is if everyone just paid attention-texting while driving creates a huge hazard.

You are why we can't have nice things. If you don't follow the rules, others don't know what to expect from you. That means you are more likely to cause an accident. You're right the rules weren't designed in a perfect world - if it was perfect, nobody would have accidents. Instead we need rules so you know what others are likely to do.

Meh, I'm courteous and watching for people as I said above. There is no problem.

I found that for many people this concept makes them feel uncomfortable, and that they then explain that discomfort by appealing to rules.

I remain unmoved.

IMHO we need less rules, not more.
