Delivery driver jobs would be at less risk, CEA forecast says. The proliferation of self-driving, or autonomous, tractor-trailers threaten the jobs of nearly 1.7 million commercial truck drivers, according to a study published late last month by the White House Council of Economic Advisers (CEA). The study, released Dec. 20, said the jobs of between 1.34 million and 1.67 million truck drivers would be at risk due to the growing utilization of heavy-duty vehicles operated via artificial intelligence. That would equal 80 to 100 percent of all driver jobs listed in the CEA report, which is based on May 2015 data from the Bureau of Labor Statistics, a unit of the Department of Labor. There are about 3.4 million commercial truck drivers currently operating in the U.S., according to various estimates.
