Curious if the rate of temp increase is equal between the two colors... does make sense that after some amount of time they'd equalize.
Of course, perception is sometimes good enough too.

That's what I was thinking. Each car would reach the same equilibrium temp, but the black car would get there first.
I think the best way to reduce the heat gain is to stop the light from getting inside in the first place. There are some window covers that are installed externally, but those are problematic (weather and thievery).

Regarding your golf ball picture. Would a racing disk gain benefit from having "dimples"? The racing disk is obviously not a sphere, but it does rotate.
(Maybe what we really need are sphere-shaped tires with dimple-tread)
