This thread was/is awesome. I remember all these things I was whining about... I was in Rome at the time and likely drunk...
Anyway, I was going to complain about driving (again). This time my pet peeve are people that don't left signal when stopped at a light.
More clearly, when a one lane road intersects with a much larger road, there tends to be a couple cars waiting to get through. So the light turns green and THEN the guy in front of you signals that he's turning left. Now you're stuck behind him while everyone else is going around him.
You didn't pull up beside him because if he IS going straight through, you have to merge back in a look like a tool, or else race him and look like a tool.
Another pet peeve is Revenue Canada. They're soooo annoying.
