I have recently embraced the "hypermiling" driving style where you spend as much time as you can coasting from light to light. The new driving style demands more attention to things like crosswalk signs, which are a great indicator as to when the light is going to change. You're absolutely right, if you miss the light you're missing the point! If I do hit a red light and know I'll be sitting for more than 30 seconds I shut the car off to save even more gas! I keep the ingnition in the on position and the AC continues to run cold for several minutes. Also, I always drive in the right hand lane and let people get around when possible - I even wave when they tell me I'm number one (;

My car is rated for 21 mpg in the city and I get 30. I save $20/tank hypermiling - See you at the next stop light!
