I guess it just depends on where you leave and the cops that are on duty. For instance, where I live I never get hassled and pass cops on a constand basis as they hang out at the gas station I pass every day. They recognize me and my car now and never mess with me. Going on 2 years living here now.
When I go visit my parents, who live in a ritzy township, I have to roll all the windows down anymore. If they are up, then I will get nailed! Have been pulled over twice in the same week, by 2 different cops and yeah, they let me go, but the hassel me about it everytime. I hate visiting my mom. Funny thing is I grew up there and lived most of my teenage years and even bought a house there and know most of the cops. I didn't know these last two, but what I think helps me get out of a ticket is me telling the cops, "hey tell Ricky, Bobby and silly sally hi from me. I know most of the higher ups there...........hopefully anymore these young cops start to remember my car. Oh yeah and it helps having the baby in the back seat, lol!
By the way I have 20% all around, which reads like 17% on a tint meter.
