People who don’t indicate before turning.
I hate them. How stupid do you have to be to cruise around completely unaware of your surroundings with no regard for anyone else’s or even your own safety?
I’ll just slam my breaks on in the middle of the road and take a left. Why the fuck not? Oh and if you flash your lights or beep your horn at me, I’ll either act utterly confused or flip you off.
If you miss your turn, carry on and turn around when it’s safe. Don’t slam the breaks on and yank it round the corner like a selfish arsehole.
