When so many people "think" they were promised something then the more likely explanation is that the promises were misleading.
I think this was Tesla's strategy and it was a winning one too. Tesla got a lot of cash from that promise, helping it be the company it is now. But the strategy is also a victim of its own success because there comes a point to deliver on the promise and you can only delay that by doubling up on the promise for so long. Then so many people start asking questions at the same time it's like a bank run. The strategy goes bankrupt unless it can actually deliver.
Tesla isn't delivering what people not only were promised, but were actually sold for real money.
Musk very explicitly claimed in consumer shows that FSD would allow your Tesla not just to safely drive you around, but allow you to use it as a robotaxi, making money for you while you're at your own job.
I would find this very rewarding and lucrative.
If Musks moonshot had been successfull, we would not be having this discussion now.
But it was not, and now Tesla is in trouble because they can’t deliver what people think they were promised.
