This one also just came to me on my way to work. People who realize they need to turn at the last minute on a divided highway and decide it's a good idea to stop in the far right lane, and cause all kind of fuckery trying to get to the turn lane instead of going to the next light, making a u-turn and coming back to where you needed to turn. Save yourself the headache and the danger for yourself and everyone you just cut off and just take 1 more minute to go to the next light.
