Affordable, accessible mobility services would upset vehicle sales, according to a new Cox Automotive study

If alternatives to traditional vehicle ownership were more accessible and affordable, consumers would be less likely to buy cars — perhaps driving U.S. retail vehicle sales down as much as 29 percent, according to Cox Automotive.

In the third and final phase of its Evolution of Mobility Study released Thursday, Cox also found that if all transportation alternatives were available nationwide, the share of miles traveled in personal cars would drop by 21 percentage points from today’s estimated 93 percent share.

The cost of vehicle ownership continues to be a major issue for many Americans, with nearly half of consumers surveyed believing it is too expensive. That makes them open to exploring new transportation methods vs. ownership — more than one-third of 2,100 survey respondents expressed interested in reducing the number of vehicles they own in the next five years.
