It’s funny you mention inspection stations not knowing the law. When I used to live in MA I took my crown vic(former cop car) to get inspected. It had 35% tint on the front windows which is legal in MA. The first place I went to said “if it’s that car you want inspected I’m gonna have to charge you to remove the tint it’s too dark” left and went to a different inspection station. The dude threw a tiny meter on it and then passed the car no problem. You’d think every inspection place should be on the same page
