I don't see too many other road cyclists blatantly ignoring the laws the way I see commuters do when I go to the city. When my son started commuting last year he called me up after his first week and asked if it was OK to do the stuff the other riders were doing, i.e. running reds and being just generally crazy. I told him no, it's not OK, you will still get there! He now likes to "race" these people, showing them that he can keep up, even with obeying the law.
Occasionally I see, mostly riders who are alone, running reds out where I live, but there just aren't that many lights. The large club rides that come through here generally obey the stopping stuff, because the police are watching, but at times, they don't ride single file when they should be.
