Who needs a new car when you have Uber?

The real potential challenge to auto sales came from the survey’s second question, which asked whether Uber users would reconsider the purchase of a car specifically because they use Uber.

According to the survey, 22 percent of Uber users aged 18 to 64, who have used the service in the past 6 months, said they were delaying or holding off buying a new car for that very reason.

Uber is a like a “Mack Truck just rolling down the street gaining speed,” said Magid Advisors President Mike Vorhaus on CNBC’s “Fast Money” this week. “So I do think we’re eventually going to see this in the numbers of auto sales.”
