The people who think speed bumps are a good idea.
The people who thought the 50 mph zones are a good idea.
Civil servants (the ones who insist on placing speed bumps everywhere, putting up new posts just because a person complained about someone parking somewhere once, the ones who think paying 1.50€ per hour is a fair parking price

.).

People using foglights when there's no fog
Inconsiderate ****'s who ram their door into yours...
People who can't park ( someone slightly scuffed my passenger rear corner recently.).
People in tiny 1.0 enigned cars who think they are racing me and floor and rev the nuts out of their cheap tax recession mobiles. ( ''People who can afford to spent £5k+ on a car but then base their choice on how cheap it is to tax. '').
People doing significantly lower than the maximum speed.
Voiturettes ( 45kph cars), I just get so annoyed when I'm stuck behind grandpa and I can't overtake.
People using full beams when I'm around.
Police officers thinking they are above the law, usually in some VW tranporter or Merc Sprinter, me doing slightly above the speed limit like everyone, they are behind me, then they put on their alarm lights JUST to illegally overtake me ( through a solid white line) when they don't have en emergency at all and turn the flashing lights off again once they're past me and then I catch up with them at the next traffic lights

.
People giving me the ugly look when I overtake them at 3am because I drive slightly above the limit at those times at night.
secondary school cyclists ( the 12-16 year olds aways think they have the right of way or simply don't care and always pull out without looking.).
People who don't cross/pull out/go when I give them the right of way even though I'm waving at them and flashing my lights telling them to GOGOGOGO...
People who are slow at traffic lights and cause me to drop to the first gear just because they didn't move for ages when the light turned green.
People who double park in places where there aren't enough parking bays.

People not keeping to the right.
People not indicating on roundabouts.
Environmentalists.
Window washers at lights ( in Poland they were annoying as hell).
Gipseys ( roma) in Poland standing at the lights begging for cash with their babies in their arms, then proceeding to return to their massive mansions in their brand new Skoda's and VW's, dirty little **** get a job rather than living a rich life without ever working. I am annoyed by everyone falling for the trick and giving them money too...
People who insist on overtaking me while I'm driving on cruise control, only to slow down right in front of me again causing me to turn of my CC or overtake them again ( and them getting annoyed at me overtaking them again).
