Given the state of the economy, I think we're going to see a lot more enforcement of previously-ignored laws in the near future. It's easy money for the City!
Personally, I have no problem ignoring some laws as long as I'm not inconveniencing or endangering anyone else - I'll occasionally ride the wrong way on a one-way street, and I'll happily go through an intersection against a red light if there's no traffic coming on the cross street. But I'm aware that it's illegal, and if a cop chooses to cite me it's my own d*mn fault.
Anyhow, if I can't talk my way out of it, I just figure it's a little more money the City can use to fix a pothole or paint another bike lane somewhere. So really, in a way, I'm just doing my civic duty! :-)
