>> I don’t know if any of the implementations are up to the mark. FSD isn’t.

Having talked to engineers in the industry over the years, I feel confident to say they are not.

It's a problem where the base functionality - following a well marked lane - is actually f-ing easy, but every nonideality beyond that gets harder and harder. So people look at the base case and get all impressed. It really takes AGI to do properly. Management looks at each failure as if "just one more fix" is all they need.
