I really need some advice on a traffic accident I was involved in.
Briefly, I was left with no room by an overtaking car. The large Toyota Landcruiser was so close I was able to bang the passengers car door with the side of my fist without my arm outstretched. I did this to warn the driver that he was in danger of running me over. He continued to squeeze me towards the curb around a left hand corner and so I collided with car and I was so angry/scared I lashed out and pushed his wing mirror forward (not damaging it) and grabbing and snapping his wing mounted aerial, this was while the car was still moving. The driver threatened me verbally with maliciously damaging his vehicle and a large scratch was identified that went down the entire side of his car. The scratch I am not sure how it was made but he blamed it on me. He was unbelievable threatening and wanted me to pay for the aerial, which to begin with I agreed because I was shaking and wanted this nightmare to end. He then said what was I going to do about the scratch, which I was not going to pay for and so requested he called the police. The police arrived after 20 minutes (typical fast service) and took his statement but not mine. They concluded it was a traffic accident and I damaged the car with my outstretched arm. They said that his insurance company would contact me and that was the end of their assistance. As leaving comment, the police officer said that next time I should stop and let the car pass if they came too close.
So now the driver has my telephone number and address given by the police, this makes me nervous of retribution. The driver phoned with a quote for the repair to his aerial that came to £600 +. I said I wanted the claim to go through the insurance and he said he was going to therefore include the scratch and it will cost me thousands. I await contact from his insurance company.
I need advice and evidence of previous similar cases that have gone to court.
I have been riding on the road since I was 4 and am a qualified mountain bike leader and have worked as a guide in the States and Greece. I am a confident rider and know when someone is endangering my life.
Please help if you can as I do not know what to do,
James
