February 28, 2019: Twenty-eight companies actively tested 467 self-driving vehicles on public roads in California last year. Those vehicles covered 2,036,296 miles in autonomous mode.[1]
The companies reported 143,720 disengagements. That’s the number of times the system had to turn control back to a human driver.
As Statista explained, “Disengagements are a key part of the testing process and they occur when a car's software detects a failure or a driver perceives a failure, resulting in control being seized.”[2]
Google’s Waymo cars had the best track record, going an average of 11,154 miles between disengagements. GM Cruise was the only other company to average more than 5,000 miles before giving control back to the humans.
The worst performers during this period were Apple and Uber. The two of them combined accounted for 97% of all reported disengagements. Apple averaged just 1.1 miles between disengagements. For Uber, the average was less than half a mile.
