Driverless Car Data Shows Robots Are Improving But Still Need Human Hands

A total of 48 companies submitted reports with vehicles traveling a combined more than 2 million test miles in autonomous mode, quadruple the total a year ago. Americans drive on average 13,476 miles each year, according to federal data, so the 2 million miles equals about the total driven by 148 Americans.

“You have to take these disengagement reports with a grain of salt,” said Phil Magney, founder of consulting firm VSI Labs. “These are after all still development vehicles, and they are pushing a diversity of edge cases. In some cases you may be running isolated sensors or algorithms to identify their strengths or weaknesses.”
