My gate opens outwards so if some goondu park in front of my house and I open the gate, tough luck.
If the owner of the car is so stupid as to park in front of other people's gate then they should be prepared to have their paint work ruined as some gates open outwards and some slide sideways.
I also agree that there should be some from of courtesy and decency to leave one's contact number on the cars being blocked and the offenders car so that at least people can call the owner to come and move it instead of just PARKING there and walking off or thinking : " If people come back, they horn and I come and move when I hear the horn..."
Really vomit blood sometimes.....
