These have already been mentioned but I would have to say my biggest is people who do not use their blinkers. I would gladly let someone over in front of me if they would just use their dang blinker!!!! And people who wait till the last minute to merge over in construction. I just love it when a semi blocks the lane way back so people can't do that!
Most of my pet peeves are driving related. To bad I have to drive a good distance to work. :(
