But the roof and maybe the pillars are more directly in the sun, especially at the time of day when heat is greatest. So wouldn't you expect something better that 30%? I could see painting green down to just below the windows too (maybe).

The authors also concluded you can boost your gas mileage by 2% by driving a light colored car, assuming the air conditioning is running.

Yes that's the study, I started
a thread about it on the 22cd. You're right that I confused the discussion of the findings slightly. I didn't go read it again before posting this. This mod is about comfort and appearance, not energy savings. I deleted the AC, anyway.
