I, for one, never knew we had to follow traffic laws. I thought we were in same boat as pedestrians when it came to red lights, etc. But here's the question...how are you getting a ticket if your bike doesn't have a plate?
Cop: Hey, c'mere u just ran a red light, I'm giving you a ticket
Me: *pedals faster, possibly making a turn up the wrong way on a one-way street*
Cop: damnit
(Not that I would ever be so brazen as to attempt such things...or would I?....or have I????)
