I once had a cop do a U turn just to follow me down the road. He thought he would be sneeky, but the U turn was on a sunny day. I was driving on a 35 mile an hour double yellow road that went on for miles and miles on a windy country road. I drove at exactly 31 miles an hour for miles and miles and miles. He was stuck behind me and I was not going so slow that he could pick me up for going too slow. I could see he was mad because he thought he had me. Finally, we came to a gravel drive way that he could turn into which he did like he was sliding into home. He must have had a call from Andy to get back to Mayberry RFD.
