I don't see anything wrong with cruising up the line at the light. I think in Chicago, it's worse to wait for the traffic- we'd never get anywhere, and on top of that, I don't feel safe waiting around in traffic- I just feel too exposed and prefer to move up to the front. When the light turns green, it gives me a little bit of a head start, which I consider to be safer for me than waiting in traffic and having everyone starting at once and forcing me over (which is usually what happens).

Besides, I think the car drivers are sooooooooo envious when they're stuck in a car and see a bike sailing past, saving a ton of time!
