I usually don't shut mine off because stop lights usually turn green by the time I shut it off anyway, and shutting off and restarting you engine uses the same amount of fuel that it would idling for 30 seconds, so unless your wait is longer, you don't benefit, and you wear out your starter faster. If I have to use a drive-thru, I shut off the engine and use the hand brake because it's downhill to the window, and I can neutral coast there, and I usually wait way more than a minute. My brother thinks it a retarded Idea, but I think he's the retarded one. Why use gas when you could use the force of gravity to make you go infinite mpg?
