Hit and run with injuries. This foreigner and his wife, if they have any brains at all. Will threaten police action like criminal charges and court action against the Thai man. As my understanding is if have this kind of accident, then can get several hundred thousand baht in claim against the driver. If they can not settle a monetary amount then the Thai man can be charge criminally and a case for damages and hospital fees can be sued for. The same as a a Thai does to a foreigner that hits them.
