I'm a bit of a stickler. For 15+ years, I commuted by skateboard and I can tell you some cops are just itching for an excuse to stop a guy on a board. I have always made sure to not give any reason for 'the man' to pay me much attention.

And as for passing other cars in the queue and taking a spot at the front of the line. Never. The cars waiting for the light, usually just passed me. Why would I make them pass me again?
