Now what I find interesting is "Americans have driven nearly 20 billion fewer miles overall this year and nearly 30 billion fewer miles since November, the department said."

Just how many gallons of fuel dose this translate into.

20,000,000,000 miles / average 15mpg? = 1,333,333,333 gallons @ $4.00/gal = $5,333,333,333 savings!
