Correct, OP has no clue.
For what it was worth, I had an 88 Black Fiero GT Murdered out in the mid-late 90s, entire windshield tinted with 50% and the other 3 windows at 20% tint. Got so many tint tickets in Westerville I had to go to mayors court. Tint was very dark. I removed the 20% and left the windshield alone because I was told they were going to inspect the car and I was unaware of the law. They sent a bailiff out to inspect and he told the judge it looked fine. I only had to pay court costs, and the judge sent me on my way. Not many officers will notice any tint on the front windshield of 50% or less, and back then the meter could not test the windshield. It could only be slipped over the window when it was rolled down. You can't roll a windshield down.
