That's what I thought too but after trying FSD on HW4 for two months I really think they are almost there. HW3 was really bad but I didn't need to intervene once with HW4. I think their biggest hurdle will be more of a legal or insurance one when they need to shift liability to actually stop saying it needs supervision.

Both of which are supervised too, but remotely, and not constantly. There's no reason why Tesla can't do the same - they probably do for Robotaxis now - as soon as the exception rate is low enough, why not?

If it is so good why don't they take liability? They aren't even willing to risk money while you are ready to risk your life...
