I'm a pretty incorrigible scofflaw rider in NYC traffic, but I don't generally do anything truly dangerous. I don't ride the wrong way down one way streets, I don't ride through crossing traffic. I do, however, run lights quite a bit.

I got a ticket last year. I blew through a red light right in front of a police officer. I didn't get in the way of any cars, I didn't startle any pedestrians, really nothing dangerous; but not legal. $50 or something. I think the citation was "improper use of a bicycle" rather than running a red light. Could have been worse; running a red light is a more expensive ticket.

Okay, that said, I totally support the police cracking down on scofflaw cyclists, even me, as long as they do it uniformly and fairly. Cracking down for a week or two, now and then, does nothing. But if they could actually change the culture, that would be great.
