Here's a few of mine:
People slowing down to 5 mph to make a turn.
Prius drivers constantly going 5 under the speed limit.
Anyone in the left lane going the speed limit or less and not moving over when possible.
Not having headlights on in the rain.
Not turning left on red when going from a one way to a one way.
Stopping at a roundabout when there's no traffic. It's a YIELD.
Anyone else?
