Few people understand the psychology of dealing with a highway traffic cop. A normal speeder will panic and immediately pull over to the side. This is wrong. It arouses contempt in the cop heart. Make the bastard chase you. He will follow. But he won't know what to make of your blinker signal that says you are about to turn right. This is to let him know you're pulling off for a proper place to talk. It will take him a moment to realize that he's about to make a 180 degree turn at speed, but you will be ready for it. Brace for the g's, and fast heel-toe work.
