Nearly 80 percent of all battery-powered vehicles in the U.S. are leased, not owned. The lopsided consumer preference for leases is fueled by a couple of factors. One part of it is a consequence of public policy meant to spur electric vehicle adoptions: buyers of pre-owned cars can’t grab thousands of dollars in federal and state incentive. The other reason is that many drivers are betting that upcoming models of electric vehicles will far exceed today’s capabilities in terms of range and efficiency.
