I'm just wondering everybody's thoughts leaving the AC on when you shut the car off/being on when you restart the car. My dad always made sure the air was off before he shut the car off so naturally I do the same. But I've always thought the majority of car owners did that. Recently I've noticed not that many people (at least people that I know) don't really worry about it. Is there advantages to doing so or am I just being overly cautious?
