I hate that if someone can't park his/her car soundly but leave it so that it prevent other people and their car to move.
Like yesterday when I was leaving home from the school. There are two parking rows in the school's parking lot. One is next to the wall of the schoolbuilding and the other is opposite that row and abut on the forest. The distance between those two rows could be something around 7 to 10 metres. Well, yesterday some egghead (somebody from a local driving school?) had parked a queue of cars in the centre of the parking lot, between those two rows! You can believe that it was hard to slalom your car out of there when there was also car next to your left and right side in the row.
