That bloke needs his head smashed in. Assaulting a young woman, given she was riding on L plates, a learner no less. Absolutely nothing wrong with her riding practice.
Just to put a serious comment on this. someone's negligent driving doesn't give someone an excuse to commit a violent crime. An anology would be like saying a person having valuables on display makes it okay to rob them. This guy has assaulted someone, he will do it again probably to someone more vunerable next time. It needs reporting to the police.
