Knock on wood, I have been very fortunate. I have 95% tint on my windows (I think Pa law allows up to 70...) and it gets a lot of attention. I was in a police station visiting one of my cop buddies (it's always good to know cops!) when this one cop walks in a huffy. He said he was going to impound the Camaro parked out front because of the tint. So I asked why he would do such a thing to my car. His attitude changed and I joked that he could take my car if he could catch me ... playful banter back and forth
I was also doing 20+ over the limit right past a cop. For certain I thought I was getting a ticket because he pulled out with lights ablazin. I roll down my windows and he just drives right by me.
Doing volunteer work and being in the military has allowed me to interact with all kinds of law enforcement, so I've been able to build up my network!
Also, it helps to step out of the Camaro in a cute dress and stilettos.
