Mine is when I’m driving behind a pack of cars and either someone merges into my lane from the center or makes a left turn across in front of me because there is space, but being me the road is completely open. I’m other words they choose to turn/merge in front of me and make me lift when they could have just waited for one car to go by. Irrational because there is just enough space for them to complete their maneuver and they aren’t doing anything wrong but why can’t they just wait goddammit.

What are your irrational annoyances Oppo?
