When people mention this, I always ask what percentage of cars are following the speed limit—a rule of the road all the more important when piloting a vehicle which can easily kill. Cyclists disregarding the rules of the road are lower percentage, and primarily endanger themselves.

Fare: I agree that cars speed more than cyclists blowing stop sings/red lights but the latter is far more dangerous in my opinion and I see them do it constantly.

I had to slam on the breaks 3 weeks ago when making a left because of a biker completely running a red light in front of me.

Count the proportion who run the light given the opportunity. All cyclists have the opportunity, but only the front car - if it stops, it blocks others.

I find the number running lights to be similar.
