Drive a newer looking pickup truck. They won't mess with you because you're obviously "good people" if you can afford something like that. Avoid driving a clapped out Nissan, because you're a bad person if that's what you're driving. You have to think like an idiot with a highschool education.
Sounds kinda like what happened to a friend of mine years ago. Cop pulls him over for speeding a bit, other people were going noticeably faster. He asks the cop why him and not some of the other people, cop says it's because he was easier to get to since he wasn't going as much over the limit as the others.
Basically, it was the "you don't have to outrun the bear, you just have to outrun your friend" of the automobile world.
