The most convincing evidence promoted by automation doomsayers, who argue that we are about to enter an era of mass unemployment, are the roughly 4 million motor-vehicle operator jobs that are put at risk by self-driving car technology.

But Deloitte CEO Cathy Engelbert argues in Quartz that even though her firm predicts that "autonomous vehicle fleets will begin being introduced in 2020," and start doing the jobs of human drivers by the middle of next decade, we shouldn't be overly concerned about the impact of the technology on labor markets.
