As has been mentioned previously – inconsiderate parking.. On safety grounds you could argue that it probably should make you go AAARGHH but it really boils my piss to whole new levels.
The main street in the small town where I live is absolutely shocking for it. Cars parking in bus stops (whereby as soon as a bus comes it causes absolute carnage and blocks the road), double yellows, disabled bays and yesterday’s absolutely howler – smack back in the middle of the zigzags on the pedestrian crossing! What really pissed me off was the AMG badge on it (a C220 DIESEL)! I had a good old shouty/sweary moment as I drove past this trying to see if people were waiting on the crossing through his car.
