The details of that video are fuzzy at best. The crash happened 8 months before it was reported in western media, before Tesla made any announcements about fully self driving systems. It's not even entirely clear Auto Pilot was involved. Still, there have been confirmed accidents involving Auto Pilot. That's not to say it hasn't been acting as designed. It is currently a system to help drivers when they make a mistake, not a way to prevent drivers from needing to drive. They've said it will do more eventually, but that's not what they're selling. It's entirely possible that Waymo's system is completely incapable of dealing with street sweepers stopped the middle of a passing lane of a highway. If that's the case, there's no way the professional test drivers would be taking the car into that kind of situation. The public isn't given that degree of insight into their testing methodologies. This contrasts with shipping systems, where the public is implicitly given a users (potentially mis)using the system. It also means that Tesla has orders of magnitude more distance of real-world test data than non-shipping systems.
