"In this graph, the authors show how the "energy cost" of transportation in the U.S. fell by nearly one-third between 1973 and 2003; that is, we used to use nine gallons of fuel for every vehicle mile, now about six. But over this same period, total fuel use did not drop by one-third (as it would under the silly static analysis employed by Mineta and Zakaria); instead, fuel use rose by more than half, from a little under 120 billion gallons per year to over 180 billion gallons."

Thats pretty simple minded isn't it?? Between 1973 and 2001 the US had population growth; the number of people driving vehicles went up. You could come up with a fair number of other variants to factor in to, I would think.
