Trucks, vans and SUV's take the hit real bad from open windows at 55, even at 40. I usually close the windows after I hit 35 and turn on the fan (no A/C). Even from winds blowing the vehicle backwards makes it harder to keep speed, making your vehicle a giant parachute isn't any better.
Do any of you have a source for this AC data or is just accepted practice?
