I normally don't shut things down in traffic, but I have always tried to anticipate lights. Coasting is a great fuel saver. Now days you're seeing fewer folks racing up to a red light just to wear their brakes out. The good side of higher fuel prices.
In some cities, the pedestrian light going solid red is an indication the light is changing. So I try to be ready to roll once the light is green.
I've always wondered why some drivers wanted to be the first to be stopped at a red light. Still can't figure that one out.
