There's nothing too special about their autopilot compared to what other manufacturers offer. Musk's fast and loose claims about what Autopilot cand do "in the next six months" or "around the corner" were overhyped exaggerations designed to sell cars at best or Theranos style lies at worse, hoping that by the time people wise up about the false promises, Tesla's engineers will have something to show for close enough to what he promised which will buy hem more time to create more hype to sell more cars. Rinse and repeat.
The thing is Tesla can't maintain their wide moat as the other manufacturers are catching up.
Grown up friends of mine were rabidly buying Tesla stock, basically putting their life savings into it, and when I asked them why, they kept telling me "because Tesla's innovations would make the other car manufacturers obsolete". Now they're pissed at him.
