Crash: The Decline of U.S. Driving in 6 Charts @TheAtlantic

Has the United States passed peak car? It's one of the more tantalizing questions that energy and urban-planning nerds are pondering these days. Ever since the recession, Americans have been driving less, getting fewer licenses, and using less gas. But is that just the work of the recession, or something more permanent? 
Over the past several months, Michael Sivak of the University of Michigan's Transportation Research Institute has released a series of short papers chipping away at the peak-car issue. They don't give us a definitive answer. But his findings, collected in a third study released this week, do a marvelous job illustrating the post-bubble decline of car buying, driving, and fuel consumption in the U.S. Here are what I think are his most interesting take-aways. 

The Average Household No Longer Owns 2 Cars

Officially, at least. At the height of the housing bubble, there were a shade over two registered cars on the road per household. As of 2011, there were just a shade under two.
