Assholes who won't move over to the completely empty left lane when I am trying to merge onto the freeway before the on 300 yard long on ramp lane ends.

Civil engineers and transportation departments that build 300 yard long on ramps because they expect the asshole to move over to the completely empty lane.

Or another way of putting it

People who are trying to get me killed.

People who are trying to get me killed and are too fucking stupid to realize they are trying to get me killed.
