Cool Vehicle

Install in all vehicles, a small quiet exhaust fan that would exhaust the interior air on hot summer days. Operated by Solar or possibly battery. This would save fuel by not over working the air conditioner. The interior could be cooled much faster and use less fuel when started. It would keep interior heat damage to a minimum.

Good idea.... I think that the Toyota prius has a simalar set up.
