national obesity problem

From a New York Times article:

The average new car or light-duty truck sold in the 2003 model year tipped the scales at 4,021 pounds, breaking the two-ton barrier for the first time since the mid-1970's, according to a report released by the Environmental Protection Agency last week.

The fattening of the nation's automobiles is a principal reason that average fuel economy has stopped improving and the nation's consumption of crude oil has been swelling: all else being equal, moving more weight takes more energy. Add in the additional pollutants and greenhouse gases released by burning more fuel, and it is not surprising that the upsizing trend is condemned by environmental groups.

[...]

New noncommercial vehicles are actually even heavier than the statistics show, because the largest vehicles sold to consumers, including Hummers and Ford Excursions, are not classed as light-duty, so they are not covered by fuel economy rules or counted in average weight calculations. They are also exempt from many safety standards and crash-test requirements.
