If you read the follow-up[0], it's not clear that the Cruise car did the wrong thing. It may have been unavoidable for the Cruise car to avoid hitting her after she was thrown in its path, and if it had then tried to continue driving to unpin her, she could have been injured much worse, or killed (say if the axle or another tire had then crushed her chest or head).
These autonomous cars have done some truly dumb things, but I don't think this incident is so obviously bad.
Meanwhile, the human driver who actually hit her first, and then fled the scene, still hasn't been found...
And that is what is the unacceptable failure scenario. It'll be cool in the future, I guess, to have autonomous taxis. But I'm sure glad they don't test these in public where I live.
