This is a difficult conversation to have for many reasons.
1. Driving culture and infrastructure are different from city to city
2. Individuals behave differently
3. People are very passionate and emotional
4. The data is difficult and everything is very situational
As a cyclist in Portland Oregon, I do feel it is safe to run red lights and stop signs in certain scenarios without being an ass about it. The key to it is awareness and agility. Cyclists have more awareness than car drivers, they can see and hear more than a driver. Second, a bicyclist is going slower and is able to turn out of the way and stop much more easily.
Of course cyclist don't want to stop their momentum, that makes sense. Of course there is risk involved. I'd rather focus on how to educate people to ride and drive safely. Our driving culture in the U.S.A is very aggressive and dangerous. We need safer streets and everyone needs to make an effort.
