Americans are now pumping 938 million gallons of fuel more annually than they were in 1960 as a result of extra weight in vehicles. And when gas prices average $3 a gallon, the tab for overweight people in a vehicle amounts to $7.7 million a day, or $2.8 billion a year.

After aggressive driving, carrying around extra weight in your vehicle is the #2 cause of higher than expected fuel consumption. But after storing the golf clubs and other unneeded stuff from your car in the garage, what's left? You.
