Many of the above niggle with me but I don't have the energy to get annoyed about them .
With that in mind, I do agree with the dropping of clothes pegs, loose/lose, apostrophes, sniffing, pronunciation of contribute, wrong usage of "myself", "yourself" etc.
I would add that there is a very narrow road up a steep hill in a town near us with a brick wall on one side. If you cycle that route there are 3 alternatives through parks or alternative streets, but cyclists insist on cycling up it. That really does make me cross as a driver. I feel like grinding them into the brick wall. Last time I was there, I saw that they were painting a cycle lane down one side, making the already narrow road even narrower for motor vehicles. When I lived there I went everywhere by bike and always used one of the alternate routes. What's so difficult about that?
AND my dishwasher projects the time still to run onto the floor, alternating with a pictogram of the stage of the cycle it is presently at. Every time I look to check, it has just changed to the pictogram and I have to wait until the time shows up again.
