Funny Math

Sorry I found this after the last post, and I couldn't help but mention it.

On the main website for "Who Killed the Electric Car" (http://www.sonyclassics.com/whokilledtheelectriccar/electric.html) they list some "facts":

Fact 8: "The United States consumes almost 9 millions barrels of gasoline daily ..."
Fact 9: "If everyone purchased on of the four most efficient models in each vehicle class, fuel economy would be 12% higher and Americans could save 13.1 billion gallons of gasoline annually"

So lets add those up. Everyone buys a nice car, and together we save 13.1 billion gallons of gas, or 13,100 million gallons of gas every year.

Daily that would be a reduction of 13,100/365 or 35.9 million. How can we save 35.9 million daily if we're only spending 9 million daily?
