       | Let's figure out how to make the problem easier to solve.

         | 
         | Most weird autopilot goofs and accidents stem from the car not
         | knowing the exact distance to the object its seeing with its
         | cameras.

             | LIDAR is still probably way easier to get right, though.

           | What about crappy roads with worn markings, missing / damaged
           | signs or out of order traffic lights? How well are these
           | handled?

       | I'm not sure about USA, but here stop signs placement doesn't
       | indicate the location to stop. Instead it is the line on the road
       | if present. Or in such location where the visibility is
       | sufficient. Fun to know that the system would fail here...

       | So basically, their self driving software assumes that stop signs
       | are all the same size and is using some simple scaling algorithm
       | to judge where to stop?

       | And this is what passes for AI? The singularity is upon us folks.
       | 
       | Just give me a simple car with analog guages and a Bluetooth
       | radio so I can talk hands free and listen to the 100+ albums I
       | have stored on my phone. I'll provide any "intelligence"
       | required, thank you very much.

         | Autopilot is kind of a scam. Marketing and economic pixie dust
         | from Elon over a basic camera lane assist system to make sure
         | Teslas attract customers and hold their prestige and value.

         | But no, FSD is perpetually 6 months around the corner for him.

           | I do not know what buyers actually expect, but the phrase
           | "FSD Beta" should sound very stupid to anyone with half a
           | brain. It means that it almost drives like a human or better
           | and it needs a bit of polishing. It is not only false, it is
           | irresponsible too in this context.

           | AI is kind of a scam --- and autopilot is just one example.

           | And will probably remain so for decades to come.

             | The self driving software packages that work, the Cruze and
             | Waymos and Mercedes of the world, are in limited careful
             | rollout. These companies and teams want to make sure it's
             | safe and robust before entering mass market adoption.
             | 
             | Tesla is one of the weakest and most immature offerings of
             | the major players, and it has been given the widest
             | distribution. It is utterly frustrating.
