Do you have any evidence Tesla could do this in Phoenix? I think that is highly unlikely and at this stage might not be possible without lidar.

  With a geofenced area you can hard-code behaviors in any area where FSD struggles. I see no reason to believe they couldn't do this – FSD can already drive quite a few places with zero assistance, and most of the hiccups seem to be around edge-cases, which are easily pre-programmed.

    Do you have any evidence that's what Waymo is doing, hardcoding behaviors in specific spots/
    • fastball 6y ago
      When I say "hardcoding" I don't actually mean hardcoding. I mean forcing the ML system to keep iterating on specific problems that it did poorly at, with human supervision. e.g. the car did the wrong thing at the intersection of 9th and Elm? Give it 100 similar situations (at 9th and Elm), let it generate lots of possible behaviors, and then have humans tell it which are correct. Then whenever a car is at 9th and Elm, it uses that training as a priority. For a relatively small geofenced area that is a reasonable approach and should work well. Unfortunately it doesn't scale to the whole country/world.

        Why doesn't it scale? That's basically how humans do it. We learn general-case rules and then we learn how to handle specific situations specifically. You can observe that just by driving through an unfamiliar city with a local. They'll feed you a stream of tricks for optimizing the drive.
