I've got a UV meter. Tempered automotive glass stops about 65% of UV light. More importantly, is what part of the spectrum (I'm guessing UVB and not the more dangerous UVA).

Windshields are laminated with PVB and from what I've heard of people with other types of UV meters (mine requires it to be slide over the glass, some just need to be on one side) windshields stop about 85% to 90% of UV light. This is one of the big reasons why dashes don't crack as much anymore.

gasstingy, it works at home because the air conditioner gets turned off. If the tint on a car could make it so people would turn the AC off for a while, then FE would go up.
