No, I can't believe it. Like most of the political stories running around, there is very little fact and a whole lot of hype going on here...
The real story is quite different. CARB was trying to get legislation passed that would require new cars to be made with a new type of paint that has a higher reflective index. The idea is that if the car stays cooler, less A/C will be needed and hence better fuel mileage (yeah its a stretch!). The paint has been successfully used on buildings already to reduce energy use. The reason no black cars? Its
not in the legislation, its a by-product. They haven't figured out how to make this new paint in the color black.
REALITY CHECK- DuPont, the maker of the paint, has come out and said that the paint is not currently, and likely will not be soon, or EVER, available in automotive form. And the legislation is dead. Someone thought they could just copy it straight over from the building industry without doing their research.
Here's a link to more info, just in case you don't believe me...
