So far Elon always delivered. Not exactly in the timeframe he said but he does deliver at the end.
Really? Tell that to the people waiting for MCU1 -> upgrade to be offered, or FSD people waiting for their invite to the early access program, or for any feature in FSD that isn't part of enhanced autopilot, or air suspension on Model 3 (gross, but hey, some people want it), or people looking forward to the coast-to-coast FSD demo, or any number of the other things that have not been delivered on.
People who actually think the value of their car is going to go up by any substantial amount *IF* FSD ever offers true autonomy are going to be sorely disappointed when it triggers a race to the bottom for robotaxi pricing and it turns out they can't actually make any significant money by whoring out their car for people to ruin.
