Unfortunately, I had nowhere else to be; there was no shoulder, no bike lane, and biking on the sidewalk is illegal there.
Anyway, what I'm saying is, biking in the US kind of sucks.
Writing as a cyclist who rides in the street, and used to ride on the sidewalk occasionally.
But going off of those designated streets can be dicey. In New York I feel relatively safe because traffic is such a crawl anyway that, aside from getting doored by a inattentive taxi passenger, you probably won't get run over at a high speed.
And then you have many of the other cities in America. Dallas in particularly strikes me as a city especially un-optimized for bicyclists despite the huge amount of land there. I mean, there's plenty of lanes for cars, and just about nothing for bikes.
An initiative to change America's non-car culture would probably take as long as it would take to make self-driving electric vehicles mainstream. And automated vehicles are probably more viable when thinking of the future, as America's population continues to age and fewer people can physically bike (or even walk).
So time, effort, and treasure is spent on changes that can be politically accomplished instead.
San Francisco actually has some decent support for bikes, and a lot of my coworkers that in the SF office go by bike, but that's because they are both dense enough and have such nice weather.
As a Wisconsinite: bikes are great. They are a seasonal and recreation activity. There are a handful of people willing to bike their 6-7 mile commute year round, rain or shine, snow or sleet. They are the elite badass club. This is not a trait urban planning can expect from the masses.
It's certainly a Bay Area blindspot to forget that most people in most of this country experience extremely unpleasant heat, cold, rain, snow, etc. a majority of the time, and see dry temperate days like our daily reality here as a rare treat.
Some of the same properties that make bicycles easy to power and easy to carry (say, up to your apartment) make them easy to steal; and there's little defense against crude and destructive methods like detaching the secured wheel or worse.
We could have full-bike lockers or other bike-parking corrals or contraptions that physically move them into an inaccessible space: bicycle goes into a slot, only comes out when verified by some means (physical or digital); but this requires space, delicate moving parts, and maintenance. But when compared to a single car parking space, the space requirement doesn't seem insurmountable.
I worked for a company that had the entire bike rack stolen. A truck just pulled up an few guy threw the entire rack, including all the bikes locked to the rack into a large truck.
Again, I don't know about SF, but Danish police don't really deal with bike thefts. That's an insurance problem, not something you waste police resources on. Of cause this makes it extremely frustrating to get your bike stolen. If you have GPS tracker in your bike you get track your bike leaving the country, the police is only rarely going to attempt to stop the thieves.
The level of density required for a bike to be a good daily commuter isn't the way a great many Americans live.
I just went and looked into Auckland's climate[0]. The record high is 87F/30.5C; the record low is 25F/-3.9C. The most-heavily populated parts of the US regularly experience summer weeks where every high is higher than that record high, and winter weeks where every low is lower than that record low. Hell, there are heavily-populated parts of the US that have weeks where every high is lower than that record low.
If anything, Uber/Lyft will increase bicycle usage, by providing a backup when the weather doesn't allow for riding.
