Passophobia

Fear of being passed in traffic causing the driver to cut in front of the person about to pass him/her. This frequently causes road rage in the driver who is trying to pass but is cut off by a slower driver with passophobia.

Hey, watch the guy with passophobia in the right lane, I'll bet he cuts in front of me before I pass him.
