FTA: "The Uber vehicle was reportedly driving early Monday when a woman walking outside of the crosswalk was struck. ... Tempe Police says the vehicle was in autonomous mode at the time of the crash and a vehicle operator was also behind the wheel." That's a very bad look; the whole point of self-driving cars is that they can react to unexpected circumstances much more quickly than a human operator, such as when some…
I have seen no evidence that any autonomous vehicle currently deployed can react faster than an alert and aware human. The commentariat tends to imagine that they can, and it's certainly plausible that they may eventually be. But I've never seen anyone official claim it, and the cars certainly don't drive as though they can quickly understand and respond to situations.
From what I've seen I wouldn't trust autonomous cars to "understand" all situations. I would trust Waymo cars to understand enough to avoid hitting anything (at a level better than a human), at the risk of being rear-ended more often. Everything I've seen from Tesla and Uber has given me significantly less confidence than that.
