This is true, cops will usually pull over someone with a sunroof open, music blasting, loud(but not illegal for example) exhaust, and tint, over a minivan windows closed and quiet with the same tint next to said car. But that's just how we like our cars lol. Not usually loud exhaust on v6's but the rest of the stuff. I don't have any visual mods, loud exhaust, or anything so my chances may be lower, but I'd still be taking chances.
And whether or not the law is fair or not is completely bias, there's really not a thing everyone in the world can agree on. I say if it's 20% or lighter on the fronts it's okay, but law says 0 tint is allowed there. It's harder to get rid of that law than it was to set it in motion.
That's funny, we had a cop that would sit in my high school lot, but only seemed to pulled over for illegal left turns since all but one driveway was right turn only.
