One time driving the car whilst on holiday, I was being followed by a car which would not drop back, or overtake, despite me giving him plenty of options to do so ( he was towing a caravan). He was too close to my bumper for several miles, and was annoying me. I saw an off road lay by coming up,it turned out to be the sort that goes off the road for an extended distance, before rejoining the road, quite a bit further on. It was pot holed, and had a very rough, bumpy, dry surface. I indicated left, quite close to the lay by, and turned off the road, sharply, in an attempt to shake off my tailgater, but was pursued at close quarters by the car/caravan combo which was bouncing up and down over the potholes, throwing up clouds of dust. I slowed and moved to the left of the wide lay by, and the car driver then came past, turning his head to glare at me with a dirty, accusing look, for presumably leading him off the road, where he did not want to go. He then carried on and rejoined the road.
