Why didn't the human hit the brake? I don't understand how this is even news to be honest. There was a human in the driving seat and he failed to stop just like the computer.

Computers have better reaction times than humans. Forcibly braking is a simple maneuver.

  > Computers have better reaction times than humans. Forcibly braking is a simple maneuver. The question isn't about the MHZ speed of a computer or the theoretical reaction time but the lack of reaction by the computer in the actual real world. It doesn't matter if this is a sensor failure, a software bug, or a slow reaction by a computer. The result is the same. A person died. From the article: *"... the lack of braking or swerving whatsoever is alarming and suggests that the system never anticipated the collision.”

Probably the human wasn't paying close attention. That is the problem with level 3-4 automated vehicles: a human who is not in primary control of the vehicle has trouble paying attention and is unable to take over control quickly if it is needed.

  Wait, are you now blaming level 3-4 automated vehicles for the inattention of the human?

    It’s a problem people knew about back when “autopilot” was just for aircraft, not cars. https://blog.prototypr.io/automation-is-making-us-dumber-and-thats-a-good-thing-e58fba16118a https://blog.prototypr.io/automation-is-making-us-dumber-and...

    Ultimately, we have to design systems for the humans that actually exist, not some hypothetical superhuman. If it's not safe for actual humans to use then it's not safe full stop. It's not like this is some new issue; it's one of the main reasons why experts have been pessimistic about the prospects of self-driving cars and why existing car companies have been reluctant to deploy heavy automation in the field.

    I think he's blaming the folks who put level 3-4 vehicles on the road presumably knowing full well that said human inattention would put people at serious risk of injury and death in the car's edge cases.

  That's why I think vehicle automation development follow the path where the computer is not in primary control of the vehicle and can take over quickly when needed. Unlike humans, computers don't have trouble paying attention.

Maybe read the article: "The driver said it was like a flash, the person walked out in front of them," Moir said, referring to the backup driver who was behind the wheel but not operating the vehicle. "His first alert to the collision was the sound of the collision."
