We're Driving Less, So Should We Stop Building New Roads?

There's evidence to suggest that America's already reached peak driving. The latest figures from the U.S. Department of Transportation suggest that vehicle-miles increased by 18.1 billion miles in 2013, just half a percent on the previous year. That's a rise, of course, but not enough to skew statistics showing that mileage has plateaued since its high mark in the mid-2000s:
