> "The driver said it was like a flash, the person walked out in front of them," Moir said, referring to the back-up driver who was behind the wheel but not operating the vehicle. "His first alert to the collision was the sound of the collision."

Call me crazy but isn't a big part of the promise of these systems supposed to be they see things humans wouldn't or couldn't? If they're just as surprised as the human behind the wheel, that feels like a problem.

Agreed! This seems like an instance where even if the car knew it needed to stop, it couldn't do so in time.

Yes, to me, this is the most relevant part of the posted article:

> “It’s possible that Uber’s automated driving system did not detect the pedestrian, did not classify her as a pedestrian, or did not predict her departure from the median,” Smith said in an email. “I don’t know whether these steps occurred too late to prevent or lessen the collision or whether they never occurred at all, but the lack of braking or swerving whatsoever is alarming and suggests that the system never anticipated the collision.”

We can accept that by the time the Uber AV "saw" the victim, it was too late to brake. But that doesn't mean we can't ask questions about what the AI actually saw and classified. And even if it was a "sudden" event for humans, was it "sudden" relative to computer reaction time? How fast did the victim move into the road that the Uber AV couldn't even brake?

Yes, the report you'd hope to be hearing from Uber is along the lines of "0.2 seconds after the pedestrian entered the travel lane the automated system identified her as a hazard and initiated an avoidance maneuver. Despite braking and beginning to swerve away, the car impacted the pedestrian 1.2 seconds later." Thats the promise the automated vehicle people are selling. But in this case it seems the car was clueless.

Every millisecond of braking reduces the severity of the collision.

> "It’s very clear it would have been difficult to avoid this collision in any kind of mode,” But it's made harder if you're speeding.

It was going 3mph over the speed limit, a perfectly reasonable speed that is still probably lower than almost everyone else on the road.
