1. People going 10 under the speed limit.
2. People not using their turn signals.
3. The worst of all: when you get to an intersection with a traffic light and it's green, the person across from you is turning left, and you're turning left. THIS MEANS YOU BOTH HAVE THE RIGHT OF WAY. AS IN GO AT THE SAME FUCKING TIME. I hate when people wait for the other person to turn and then go.
HERE I DREW A PIC!!!!!!!!! /froth
