Personally, I like tinted windows. The X is the first truck I've owned with privacy glass, and I love the fact that half the time, no one can see in those windows. I wish the two front side windows were the same tint. Cools the truck down, and keeps and air of mystery around it. Dark backpacks and other items blend in to the floor and seats, so the X looks empty in a dark parking lot to anyone walking by.
Besides, I'm not driving a fucking fishbowl. No one needs to see who I am, who I'm with, what I'm doing, or what I've got. I don't want ANY involuntary personal interaction with my fellow motorists. I want them to wonder if the person who just made that lane change is a 90 lb. female, or a gang of pipe-swingin' Samoans out to rape and pillage the countryside. If someone can size you up, the advantage may lie in their court; if they can't, they may not want to take their chances with the unknown.
It also increases the invisibility factor; if no one can see you, they can't make any assumptions about you. You're not a person; you're an automobile with no driver and no personality, no culpability, no accountability. No eye contact? Move on. There's shelter in that, and safety, for those who know how to use it.
As far as the cops go, if I get pulled over, they can ask me to roll them down. I'm not here for their safety, they're there for mine. If they wanna pull me over, let it be for something legit like a traffic violation, not because I look a certain way. Let them ogle someone else. Everybody knows profiling is effective, and in some ways it is, but when you're the one constantly getting profiled, and pulled over, and searched, and questioned, and detained, time after time it starts to make you a little pissed and a little paranoid. I've had this problem since I was able to drive, being of the racial persuasion that I am.
A few here may share my experiences, and can understand my reasoning. For those that don't, please keep your unqualified opinions about profiling to yourselves. I don't give a fuck about what the 38 year old white guy in the Lexus thinks about profiling; chances are he's never been on his stomach in a grease spot with a Beretta 92F shoved in his temple...six times in the past three years. And never been charged.
I can't say I'm too surprised at all the Ricky Ranger responses here. I'm reading "but a law is a law", and "you get what you deserve", and "the laws are there to protect people", but all I'm hearing is "Baaaa-Baaaaa!"
How's cop ass taste, anyway?

*This excludes all people who tint their windows too much to see out of. Those people are just plain stupid, and don't deserve to leave the house.
