A couple of questions about hypermiling: 1. Have there been any studies that prove that driving on the highway with the windows open significantly decreases gas mileage? If so, where can I find them? 2. Have there been any studies that prove that using the air conditioner in the car significantly decreases gas mileage? If so, where can I find them? 3. Does shutting off my car (2006 Corolla) at stop lights/signs decrease the life of my car's starter (or any other parts)? Thanks!
