Things are starting to improve. The offending driver rang me on Saturday to apologise, and to give me his details and his insurance company as well. He said that on the night he panicked, and that his conscience was bothering him. I suspect more likely that the police caught up with him and told him what was going to happen in court if he did not come clean about it all. My insurance company is now working on him, so hopefully things will work out in the end. Cheers.
