@ncweaver As the article mentions though, Google has a track record of just killing off any service that isn't quite working right this instant (which is quite a lot of them). I can entirely believe that it was just Waymo's turn for the hammer to fall, without that necessarily indicating that the tech is impossible to get right.
(I mean, I think actual fully autonomous get-in-and-tell-the-thing-to-take-me-to-the-other-side-of-the-continent driverless vehicles are some way off yet. But I do think we'll get there.)
