I've been pulled over on my bike before, and know many people whom have received tickets. I really think it is a matter of perspective. Riding or walking I can't tell you how many cars I see running red lights and wish there was someone there. It's made me a more cautious rider and driver. On the flip side when stuck in traffic in a car, you see bikes passing and basically go on red after stopping. When not in a car the perspective of getting hit by a giant piece of metal breaking the law is more real, and when in the car, the comparative movement of cyclists is more apparent.

I wish everyone was ticketed, every time they pulled a fast one, regardless of car/bike/pedestrian(j-walkers you know who you are!).
