Yes, but if it's on private land, no penalty points or anything else can be given by the Law. And if one shunts the vehicle out of the way and damages it, security cameras could be recording the lot and you would probably damage your own car in the process. In UK, any action by a victim involving verbal abuse, physical assault, damage etc is a crime, no matter what the nasty perpetrator has done to you by obstructing your exit. And even on private land, those actions are considered a criminal matter. It's a no-win situation. I would very much like to 'inconvenience the offender', but how?
