Even when I cycle (which implies speed much lower than for a car) I sometimes notice pedestrians in dark garments (without reflective elements) at a small distance and have to brake hard (moving light beam up would help to see them further but it would blind both pedestrians and other drivers).
If it is difficult to see you, especially at night, it is dangerous for you and cars (obviously more for you as pedestrian) even if drivers are prudent. Help cars and help yourself by being visible.
Pedestrians wearing dark clothes at night are almost invisible. Until we put sidewalks and bright crosswalks on every street in the country, wearing reflective clothes is common sense. Comparing that to a helmet mandate is absurd.
No, someone who pops out to the shops should not have to think about putting on reflective gear, someone who goes out in a car a night should be the ** aware pedestrians exist and know to turn their lights on.
The idea that innovations demand normal folks to change their way of life is absurd on the face. Very simple measures, like major consequences for all vehicle-pedestrian collisions would solve this better.
There are already major consequences for hitting a pedestrian.
To be charged with vehicular assault or manslaughter you have to prove intent, most of these collisions are a result of mild negligence or even poor roadway design. Many states don't have any kind of charge for negligent collision that results in jail time. And yes if you kill or injure someone while driving distracted I think 3-6 months in jail is still pretty minor, given that consequences can be permanent.
For instance, in many cases, when a car has injured a cyclist severely, there could have been infrastructure to prevent this (e.g. separate bike lanes, clear road layouts, …). A helmet would not have prevented the accident.
Similarly, unless someone's crossing a dark street at night without looking for oncoming traffic, why should pedestrians have to be wearing reflective gear all the time, when there could be well-illuminated crosswalks, slower driving speeds, speed bumps etc.?
(I'm not claiming there aren't cyclists ignoring red lights or pedestrians randomly crossing roads in unsafe situations … that's usually the next argument.)
If it is dark and there's traffic it is safer and useful for everyone to be visible. Obviously this depends on how well the streets are lit, if they are very well lit it may not be a big issue.
As a pedestrian at night (which is pretty much any commute to/from work in winter in the UK) I know that sometimes cars don't see me or see me at the last moment if I wear dark clothes, or even any clothes that are not high-viz.
And as a driver I know that this is because pedestrians, or even cyclists at crossings, can be very difficult to see in low light conditions (good forbid there's fog as well!) even if you're driving carefully.
This is all common sense, really.
In my neighbourhood, which is residential and poorly lit as many are here in the UK, people also wear lights on themselves when they walk their dogs in the evening, and they usually also make the dogs wear lights.
When I go running in the evening I wear a high-viz jacket and one of those chest lights so that I can be seen and can see the potholes as well.
Again, common sense for safety in such conditions.
For example:
When it is cold, we wear protective gear to keep us warm.
When the UV index is high, we wear protective gear to protect our skin.
When it is dark, we wear reflective elements to be seen.
Obviously not everyone subscribed to that thinking, and it is not my intention to shift blame.
The pedestrian now has an independent choice to wear clothing that helps make themself visible or clothing that makes them harder to see. Their own safety will be affected by their choice.
I wouldn’t pass a law requiring it, but I do choose light/visible clothes for myself and for my family when out at night.
I don’t see why we couldn’t require some reasonable action from pedestrians, too. I’m not suggesting pedestrians should become Christmas trees, but things like “don’t be dressed in Vantablack” seem reasonable to me.
Firstly, though, street designs should aim to have street lighting wherever car drivers and pedestrians are expected to interact.
