By NYS law, factory tint can only be placed on the Back Seat side windows, and on the Rear window; If you have two, side view mirrors. the Fronts must allow a minimum of 70% light transmittance. That ='s 30% tint. The rears can be painted black!
The front seat side windows and windshield usually have about 6% tint or 94% light Transmittance to begin with. The Strip on the top is for Sunglare and is the Only legal Factory tint on the front windows.

I can't believe that there are 50 different factory tint settings to comply with laws governing window tints. So I would suspect that the Factory looks at the most restrictive states and makes the windows based on thoses state's requirements. Then the windows will be legal in all 50 States.

I don't know if the '07 model year left the sunglare windshield tint off on purpose or not.
