Our neighbours across the street parked right across the footpath, on the nature strips, facing the wrong way in the street, sticking out so far that you can't fit a car between them and any car parked outside our place etc. All it took was a few anonymous notes from several neighbours (including us, heheh) and a visit from a city council officer, who, incidentally, nabbed someone else in the street for illegal parking when they only did it the one time...but not them, go figure. After that, they stopped doing it.
Someone did egg one of the cars there, though, but we think it was an angry ex-boyfriend of the girl who owns that particular car, not because of the way it was parked. There's always random shit going on over there... but i digress. Vandalism like that is just a total overreaction.
