I thought it was illegal to have the front windshield tinted but I keep seeing the new 6 and 7 series with tinted front windows? I can tell when it's tinted because of my polarized sunglasses. Cars like the the new Mercedes S-Class & the 2010-2012 Range Rover models have them too. Am I crazy? I see them on pretty much every one of those I see so I'm guessing its factory.
