Five Billion Gallons Saved

Yup.

Driving less saves gas.

Travel on all roads and streets changed by -5.3% (-12.9 billion vehicle miles) for November 2008 as compared with November 2007. Travel for the month is estimated to be 230.4 billion vehicle miles.

Cumulative Travel for 2008 changed by -3.7% (-102.1 billion vehicle miles).

Figuring a nice, round, 20 MPG average, that's a reduction of 5 billion gallons of gasoline consumed last year.
