A road gnat is a driver who fluctuates speed so extremely that they are neither possible to pass nor cruise behind. They spend most of their time in the left lane, however they are also often found in the blind spot of cars attempting to pass.

Many blame road gnats on Obama and global warming. However, there is evidence that road gnats have existed dating back to the invention of the car phone in 1942.
I should have been there an hour ago, but I got stuck behind a road gnat with some serious road rage.
