I would report it but to be honest I doubt anything will come of it. For example, a customer of mine picked up her daughter from school last week and whilst walking along the path, some inpatient boy racer mounted the kurb and drove along the path a fraction away from her daughter, all because he couldn't be bothered to wait behind another car whilst waiting for them to turn right. She got the reg and reported them to the police. They told her she needed a witness and needed to fill in endless amount of forms etc, otherwise they couldn't do anything about it.
Worth giving them the reg, but don't expect too much from them.
