This morning I witnessed an accident between a wrong-way cyclist and a vehicle turning right out of a parking lot. I reached the scene just as the driver was telling the bike rider that she would pay for damages. When I said that she was not at fault the bike rider began to dispute with me. At that point I'm afraid that I lost my temper and began to lecture him, saying that a bike is a vehicle, that he needed to follow the rules of the road, that he was lucky that he wasn't dead, etc....I told the driver to call the police so that there would be some record of the incident and at that point the bike rider decided to leave the scene on foot, abandoning his damaged bike. An officer arrived but since there was no damage to the car and no serious injuries he just took our contact information. Before I left I told the officer that I would appreciate if he and his fellow officers would watch for wrong-way cyclists and stop any that they see.
