That's fair, in a game as crazy hard and complicated as self-driving, I shouldn't have implied it's a lock, I don't think anything is a lock when that much cutting-edge technology, complicated institutional incentives, regulators, and a topic guaranteed to interest the public all come together. I meant to say "I've ridden in Waymo vehicles, a number of times, in non-trivial situations, and it was flawless, so while I'm sure there's a long tail of crazy hard scenarios, it can drive you to and from a restaurant in heavy traffic that involves getting on something that sure looked big enough to be a freeway, getting back off it without trouble, and parking better than any human I know". How much they spent to get there, and if they're ever seeing that back? I wouldn't know where to begin estimating that. I'm basically sure from first-hand experience that Waymo can do the vast majority of the driving I've ever needed. Maybe it can't cope with insane weather or something, but most people can't really either. Do the economics ultimately make sense? Dunno.
