I have seen this many times. I used to work 3rd shift, driving to work at 11 at night on a 3-lane highway, no-one else on the road and some jerk needs to ride my bumper. Pull into a different lane and he zooms way up to the next car on the horizon and rides his tail. Whatever...
The other one is people getting behind a truck and getting mad because they can't see around them and the truck won't get out of their way. Hey, if you backed up two car lengths you could SEE that you have completely empty lanes to pass on either side. Nope, staying right there headlights to mudflaps getting steaming mad.
