Im gonna have a rant so apologies.
What annoys you about other drivers, there's been 2 things in 2 days that have got to me.
Yesterday some wally driving like miss daisy in the slow lane of the m25 as I'm joining from a slip lane. I make the main carriage in front of him, a good 5 car lengths at least in front of him, look over my shoulder, see no other vehicles in any lane so I accelerate across into the fast lane. He flashes me, why flash me, I can only think that it was because I did not indicate whilst performing a manouvre that had no baring or impact on his driving whatsoever. Because he will indicate very time he does anything even if it is of no benefit to their road users. Just one of those people who thinks he is better than everyone else.
And today
Coming home from work, I'm in the middle lane and need to come of at the next junction, little bit of congestion but nothing major. I'm indicating, a gap becomes available, the next car a vw passat, at least 4 car lengths back, doing a consistent speed, I pull across, I'm now fully in the lane and the passat has accelerated hard up my arse and then honks at me, obviously missing my whole manouver, driving past me on the slip giving me the ****er sign with two young kids in the car. Prick.
