report this to the police, he or she is obliged by law to stop and give details of themselves at the road side if involved in an accident, if they failed to stop at the time and they knew they had an accident and have not reported it to police within 24 hours they can get summonsed, for failing to stop, careless or reckless driving failure to report and a whole host of other offences so get down your police station if you havnt already? and get them stuck on the slimey shite driver!!!!
