An act of road rage provoked by a motorist driving slowly while hypermiling (driving in a manner that attempts to use fuel sparingly)
When the driver of car #1 was letting the car coast up a hill way below the speed limit, the driver of car #2 was so upset that he passed and blocked his path. This was considered a hypermiling tantrum.
