Isn't that against the law anyway, reversing on to a public highway?
Agree on the rest though. I think this is generally a sign of society and the way it has gone or is heading. People in general just don't care any more, everybody is becomming selfish and self-centred, intent only on themselves being 'ok'.
Peoples driving standards really annoy me, I do my best to drive at a sensible distance away from people, indicate my intentions, get on the side of a junction I need to be (this winds me up, people turning right but so far left you could get another car up their outside), be polite and acknowledge other people. Even as a pedestrian, saying thanks to people who stop on crossings.
The little things go a long way..
