I'm waiting in vain to be contacted, paid for the FSD upgrade in 2019, getting very impatient. But I have never been promised driving "without any user input" except as a some day target. It's not something you can buy off the shelf anywhere, for any amount of love or money.
I've been designing and coding control systems for decades. When humans set out on a difficult task that's never been done before, they always underestimate the difficulty. If they didn't, they'd never even start. That optimistic vision leaks into marketing materials and pep talks, in good faith.
Then during development, with the design changing daily, engineers have to keep explaining to people who have no idea "why it's taking so long". When they get there, to that "some day", five times over schedule and budget, it's great. But if you know anything about working in uncharted territory, you know that nobody can fully anticipate all the obstacles, or predict the time-line. You can't nail down something that has never ever existed.
Honestly, either you're looking to participate at the bleeding edge of automotive AI development, and you get excited at every step along the way, or you should stick to the well-beaten past, and leave that full self-driving to us dreamers.
