The video is out. And without a doubt a driver in full control, in the same situation, would not have had time to react.

The Uber driver did not seem to be paying much attention. I wouldn't have either. Nor would you. The point is, and it's obvious, there was no time for a human to react.

However, one might easily have expected radar to perform better. In this instance, self-driving fared no better than humans. Not a great performance.

Would a Waymo vehicle have done better? I suspect so, but I do not know so.
