This is FUBAR, and something I can speak to with plenty of experience. FSD is good enough that insurance companies are offering discounts to use it. It has a lower crash statistic than a human driver, thats not fucked up reporting, that data submitted to the DMVs which involves mandatory collection. Personally, I have used FSD for over 90k miles on two Model X vehicles. It works, and it works. well.
But to imagine that Elon Musk doesnt deliver:
1. His rockets land.
2. His space internet has 10,000,000 subscribers and climbing.
3. His brain implant has give multiple paraplegics abilities.
4. His home battery created an industry of solar batteries at scale, and they contribute to keeping peaker plants offline.
5. He has the worlds largest EV charging network.
6. Tesla is profitable and out-producing big-auto on EVs. A "Tesla Killer" is now the same thing as an "iPhone Killer".
7. FSD works, and you can have multiple end-to-end autonomous drives yourself, if you rent or buy a Tesla.
8. Elon made SpaceX profitable to the point it no longer needs NASA / US Government.
9. His companies have paid back all the loans and grants the government afforded it.
To your point:
Robotaxis...have directly caused a crash on average once every 45k-65k miles.
Citation needed. But let's give you the benefit of the doubt. Even if that were true, this is like saying stop pursuing the automobile because it will never be faster than a horse. With all things tech related, the incremental ratcheting improvement will make alternatives (human drivers in this case) eventually seem silly for how incapable we are at driving. 50K road deaths in America will be a thing of the past, sooner or later, and it will be Tesla that delivers that, because they're the ones pushing the envelope.
The guy is off on timelines, but the proof is in the pudding. Maybe you just dont like that a guy who has different politics than you is vastly more capable?
