We call that profiling bait here in CA. Goid friend averages $600-$800 a week removing tint from front row windows. Those are all typically I5 corridor. Which is the Mexico to Vancouver northern route.
Anything over I think 10% in the front 3 windows is illegal in many states. The issue being you cant make eye contact with the driver. Meaning you can’t tell if they see you, or are paying attention. It can go against you if you get in an accident also.
Most good tint shops will warn you of these things prior to tinting front windows.
