Americans are burning nearly 1 billion more gallons of gasoline each year than they did in 1960

This might have something to do with more cars and drivers maybe ?

The amount of extra fuel consumption blamed on weight gain since 1960 — 938 million gallons — would fill almost 2 million cars with gas for an entire year. However, that is only 0.7 percent of the total amount of fuel consumed by U.S. passenger vehicles each year, Jacobson said.

Yeah, I bet they never considered the 'more cars' angle, though :D

i wonder what the difference is in Insurance rates, between 1960 and now?
