I've found that polite respectful behavior goes a long way. Pull over quick, keys on the dash beside my wallet, window half way down, hands on the wheel. A couple of stops, the cops had the courtesy to not just laugh at me. They showed great restraint. Try to have your hat brim to the front and your pants at waist level.

We had a local independent spirit who claimed that only the sheriff had legal authority, when stopped buy the highway patrol. He forgot about the part where cops carry shotguns. Guns pointed, a window broken, and he was ejected, cuffed, truck towed, and he had the law explained to him. He was a slow learner, as he had decided paper money wasn't real and that he didn't have to pay his mortgage or lose the building. He became involved in a live action SWAT exercise and came close to getting shot. Apparently when he read the Constitution, he missed the part that said the SCOTUS was the decider.
