similar thing happened to a friend of mine
single track lane (my driving a white van) .......... a meeting in the middle except my mate came to a full stop and watched while the other guy skidded to a halt into the front end, he bounced off and landed in the ditch
on the road, the guy admitted he was going to fast, by the time the insurers were informed it "somehow" got flipped and "he rammed my car into the ditch"
went to court, my mate was found 100% guilty and all costs went against him - so whilst in reallity it would have been at worst 25/75 in his favour ......... he suspects that because he was a white van man .......
