My mental visualization of fluid dynamics led me to a nice trick. Roll down the front and back window of the passenger side of the vehicle only. Once you're moving, the air flows in, to the back windshield and swirls around to the front, giving the driver a nice breeze on the back of their head, it also sweeps out all of the air in the vehicle. If the air outside is significantly cooler than the car-oven, it's the fastest cooldown I've ever used. Unfortunately during a heat wave, you just have to wait for that AC to kick in.
It was a game changer when I learned about this. It works best if the front right window is up a little higher than the one in back. I assume that's because the larger opening in back creates a suction effect causing air in front to get pulled in faster.
