Several problems, which could be solved my municipalities, and illustrated by this twitter feed:
https://twitter.com/lyoncorrompu- Cars stop on the bike lane: It may sound reasonable to stop on the rightmost lane, but in fact they obstruct both the bike lane and the car lane. It would be more reasonable for cars to stop on the car lane.
- Red lights: It's less dangerous for cyclists to ride the red light than the green light. It's incredible, but there are less accidents, even if the cyclist does it every day and isn't fully aware of his surroundings. But car drivers go crazy when they see a cyclist burning the red light (which isn't surprising because it's a penal infraction in France, like drunk-driving).
- Bikes riding in the sidewalk or the wrong lane, sometimes in the opposite direction, by night, when there are other solutions. Most infractions could easily be sorted out by the police, but they're more busy acting like they're fighting terrorism (by stationing under the Town Hall palace with weapons drawn out) than checking for traffic infringements.
- Pedestrians walking on the cycle lane, which is prone to injury, often due to cars who park on the sidewalk.
- Bikes without lights: That's not much of a risk for the cyclist, because they know very well they may die from their own mistake and get a Darwin Award of stupid deaths. No, I'd rather focus on the risk for the car drivers, who will be considered guilty of killing a cyclist, even though he was in the dark without light, sometimes in the opposite direction than he's supposed to be. Bikers without lights are a jail threat for all car drivers around.
- Also note the counter-intuitive feat that not requiring the helmet saves more lives across a country than the compulsory helmet law.
All in all, if justice were served, cars should be given the short end of everything because they kill massively in four ways (accidents, immediate pollution, carbon emissions, driver's health) and occupy more space.
