I mean, Tesla demoed, promised, and took reservation money for a roadster reboot that _also_ didn't contain any technology China didn't have in 2017, and at this point they still haven't delivered on that and it feels safe to call it a scam.

Just because the technology is technically feasible doesn't mean that a specific company is not scamming you when they promise it.

And Tesla already has enough of a history of fake promises (your tesla will be a self-driving robotaxi earning money while you sleep within a few years, FSD will take you across the country while you sleep by next year, humanoid robots, the new roadster is taking reservations now and will deliver soon, regulation is the only thing holding up FSD, etc etc).

To be fair the main reason why FSD hasn't been a wide spread thing is mostly due to local regulations. The technology exists and performs fairly well. FSD is allowed in pretty much all the same cities Waymo is allowed to operate so we can see from this that its a regulatory issue not a technological one.
