U.S. vehicle miles driven have dropped. And it's probably because the size of the fleet has been in decline.
I felt like I should pull out Occam's Razor over the weekend when I spotted, via Twitter, some speculation from Joe Weisenthal of Business Insider and later Matt Yglesias of Slate about why the number of vehicle miles driven in the U.S. has been dropping.
Weisenthal toys with out all sorts of correlations to explain the decline — everything labor reductions to gas prices to an aging population...and of course e-commerce! This last part is what Yglesias picked up on. By the time the these two had finished, they'd trotted out no less than ten charts. Here's Matt:
One very interesting social trend we have going on in the United States right now is the decline in vehicle miles traveled, which initially looked like a mere recession thing but seems to be continuing even as the economy has added jobs for the past 18 months. Joe Weisenthal was speculating on twitter that online shopping might be the reason.
