So, if a car has properly left at least 3 feet (that's the law in Colorado, I know some states have it at 4 feet) then even if the cyclist has to leave their lane by a small amount to avoid an obstacle then it shouldn't be an issue. Hence the reason for the law. If the obstacle is big enough that they need to swerve more than that then there shouldn't be anything sudden about their movement and they should have plenty of time to stop if that's what is necessary for the situation. Frankly, if I were in a situation where I had too much traffic coming up behind me and I couldn't stop I'd take the risk that the object would cause damage to the bike or a crash in hopes that I'd still avoid the collision with the car.
But what I don't understand is why you and
@François Pugh are so adamantly arguing about how legal laws don't protect us physically. I'm pretty sure all of us who road bike are well aware that regardless of who is legally correct in a situation the cyclist is going to be the one physically hurt or dead. What's the point in posting repeatedly to point this fact out?
