Holmes: You have a Lidar problem. Tesla: But we don't use Lidars! Holmes: That's the problem.

  Humans don’t have lidar. If machine vision isn’t good enough to drive a car at human levels without lidar, then it isn’t good enough yet. (IIUC, it is superhuman overall but with some really dumb edgecases where humans go “well that was obviously wrong, why didn’t it see the thing?”)

    But that's only because our edge cases and the machine vision edge cases don't match, since the underlying concepts are different. And frankly, we probably don't want them to match. The main goal should be to make the cars drive better than humans on average, even if they're not perfect. And we know that there will always be edge cases.

      Agree they should not match, however I think it is also important that people trust the tech, which in turn requires it to not make any mistakes we would consider obvious. People are really bad at estimating risk, a problem which I think will be easier to overcome this way. A system which makes exactly the same mistakes as a competent human but never gets tired, never uses the phone, has 360 degree vision with no blind spots… even that would be a huge improvement over the status quo. On the other hand, a system which crashes because it missed something Joe Average calls obvious when they see the black box pictures on the news… that system will never be trusted enough to replace human drivers, not even when it has a tenth of the fatality rate.
