I am one of the lucky ones out there. I have an 05 Altima 2.5 SL with a presidential limo tint of 3% all around and 0% trouble from the cops. Never been pulled over and I've had this tint for over a year...
The trip part about is that I get more hell from the shops that do inspections and they won't pass me. I got turned down 3 times in Abilene, TX where i'm in the Air Force. They failed me for tint being too dark and my windshield strip tint was past the AS-1 line but I got that trimmed down.
Eventually I got passed in San Antonio, TX by a shop my friend's dad knew of. Unfortunately it is exactly a year from when I got that inspection already and I'm due for one this month...
