There are some scum bags around. I shunted into a woman at a junction 2 years ago in my focus who pulled forward and then stopped. Just touched her rear bumper and crazed it. She called the police, ambulance, vehicle recovery. It was pathetic. The policeman even told me he didn't know why she called him. When I renewed my insurance and they asked about the incident and how much i thought the cost was. I said max £500. They came back and told me it was settled at £9k !!!. I reckon she claimed injuries, loss of earnings, all sorts. I told the insurance company at the time I thought she was going to take them and me for a ride. She was in an old BMW which looked like it was worth about £500 to me. I just hope these people get what they deserve. I firmly believe in what goes around comes around.
Good luck with whatever route you take to resolve this.
