Really sorry to hear about all of this. If the other driver wants to be a prick and go with the cops saying it was ure fault, ure going to be in for a hard slog.
I was involved in an accident in feb,
the cops have backed me fully, and we're not even 1/4 of the way thru the legal process...hes a 68 yearold greek, stubbon at that.
I suggest going round and talking to the other driver and seeing what his moves are, do everything u can to speak with the cops to get the correct information down.
Insurance companies should get 10000x pics of every car, should be easy to tell whos at fault from there?
Making a court case out of this is not hard at all, though time consuming and the earlier u start, the better. If you go this way, I'll help u as much as i can so just ask.
