Discription of Events: Driver likes to tailgate motorcycles. I motioned for him to give me some space (less than a car length at 55mph), and he got closer to me. There were no shoulders for me to let him pass, so I pulled into a parking lot at the first opportunity. He pulled in behind me, cut in front of me, and blocked the road on the other side of the lot. I got back on the main road and took off. Extremely dangerous and confrontational!
