I think driving with your windows up is stupid. If its hot outside, you'll die or dehydrate. That's if you don't fog up your windows and crash first.
Or you can drive with your A/C on and overheat your car.
I drove with my windows up at a track in South Korea in the summer...it SUCKED! You were NOT allowed to put them down.
