i have a neighbour like this - believes the road outside his house is his (including anything within view), and a no parking zone. He also has a double drive and garage, and only one car, so isn't based on access to his vehicles; he has dropped kerbs and no-one has ever blocked those. He has called the police out to move an ambulance that was attending to another neighbour, threatened his neighbour across the road, and taken photographs & video of people parking so he can report them. Popular guy.
He's even spoken to my wife when we had building work done, as one of the builders was parked on the road opposite our house (not even his). He's only done that once though, as when I got home we had a frank discussion.
