There aren't any self driving cars on the road that don't have a safety driver, and the ones that are out there get confused all the time. The Uber one had a software dev turn off the lidar sensor to test the computer vision at night and it ended up killing a woman crossing the street.
Most self-driving is done in warm climates, in a circle. These companies are amassing thousands of empty miles on the same streets every day to impress people who don't know any better.
I lived on a branch of the main Google circuit, and often they were the only traffic for most of the day. Even saw three Google vehicles in a line, but two were more common.
What's the value of "self-driving" with no weather, traffic or route variation? PR and regulatory filing stats.
Last time cruise made a report about disengagements (where the safety driver had to take over) it was one every 5000 miles driven. That's 1 crash the car was prevented from every 5000 miles. Humans crash once per 70000 miles.
