SACRAMENTO, Calif.--California's air regulators last week began crafting rules that would force automakers to install windows that do a better job of reflecting sunlight. The goal is to keep car interiors cooler, which would reduce the use of air conditioning.
The proposed legislation requires 75 percent of passenger vehicles sold in California to have windshields that block 50 percent of the sun's heat. It would go into effect in the 2012 model year.
