I follow most rules, most of the time. I may not come to a complete stop at every stop sign, but I can guarantee you I pause at the intersection before proceeding for a longer time that most cars who come to a complete stop do. I will occasionally run red lights after stopping and checking carefully to see that its clear. I consider rolling slowly through a red to be the same as jaywalking. Going through downtown at bike speeds, you don't get the advantage of the light timing that allows all the cars to move through many lights in a row. On the bike, I would have to stop at almost every light because they aren't green long enough for bikes to make 4 or 5 in a row. I'm lucky if I can make two.
