In my very recent test drive, it (a) flashed a message that it couldn’t tell whether I was looking at the road because I was wearing sunglasses and would continue operating anyway and (b) very nearly caused a collision due to an inappropriate maneuver in an intersection. For an optimal driver-assisted recovery in the latter incident, I needed to have been paying rather close attention to the navigation, the lane lines, and surrounding vehicles, starting before the incident, and I needed to take a rather fast and considered action. It was dicey. But this would have been a complete nonissue if I were _actually driving the car_, because that’s how humans work. The middle ground of not driving but being ready to override instantly is simply not how humans work.
