In recent weeks I've found myself driving in downtown SF congestion more than usual, and observed Waymos doing totally absurd things on multiple occasions.

The main saving grace is they all occurred at low enough speeds that the consequences were little more than frustrating/delaying for everyone present - pedestrians and drivers alike, as nobody knew what to expect next.

They are very far from perfect drivers. And what's especially problematic is the nature of their mistakes seem totally bizarre vs. the kinds of mistakes human drivers make.

The unpredictability was jarring to me as a passenger in a Waymo.
