that seriously fucks me off too. i even had one twat beeping at me when the filter wasn't on an the light was at red. idiot. general ignorance on the roads annoys me - lack of indicators, people using their phones whilst driving, boy racers at traffic lights (if i wanted to, i could totally beat their citroen saxo/ford fiesta asses, but i don't because i'm not a dick), people totally driving up my ass etc. saying that, i'm actually a really calm driver and have only used my horn once when some idiot almost drove into me on union street.
