And there is a huge difference between rolling through a stop sign and rolling through a red light. I don't think the former is that big of a deal for both bicycles and cars, and I think the latter is a big deal for both bicycles and cars. I rarely see cars just decide to not stop for a red light, and I see bicycles do it on a weekly basis. I'm not talking about stop at a red light, look and see that no one is there, I'm talking about just go straight through a red light without slowing down.
There is large area between running a red light at 90mph without even batting an eye, and coming to an almost (but technically not complete) stop before continuing through an intersection with a stop sign.
