i guess it's different in FL. There are plenty of cop cars rolling around with illegal tint. I've got 6% all the way around on my car.
The sun will kill you other wise.... bare minimum in FL is 20% if you park your car out doors most of the day.
Some times they mention it but usually don't do anything. Never bin pulled over specifically for tint though. usually something else and they mention it. When a cop pulls up behind in traffic i usually open the sunroof shade and roll the windows down. Just in case.
