In the second round of tailgate testing, there was a rather neat
demonstration of E=MV^2, otherwise known as 'going twice as fast takes four
times the effort'.

They ran the test at ~50 MPH (55?), and used 5 gallons or so.  The next run
was at 25 MPH, and only used 1.25 gallons.  (#s might off a bit...)

They never commented on it, but it was interesting to see a 'real life'
example.
