I'm afraid any cleanliness advantage is temporary. People are filthy enough in cars driven by actual humans, can you imagine what they'll get up to when there's nobody at the wheel?
Yeah, I'm sure some of the experience quality is because the only other riders are people Waymo selected for the beta, and nobody wants to get kicked out for misbehavior. We've joked a few times "don't forget that water bottle, I don't wanna get banned!"
On the other hand though, I have seen misplaced items in Waymos a couple times and when I reported them in the app they pulled the car for cleaning ASAP. I actually did leave a water bottle once - a disposable, single use one - and they emailed me asking me if I wanted them to return it! That kind of vehicle management feels more like a benefit inherent to centralized taxi fleets than a benefit inherent to AVs, but it's something Waymo can take advantage of. I would guess the in-car cameras would be capable of detecting vomit-related events etc too.
I didn't know they had those. Wonder if they'll eventually add a mode where you could opt-in to livestream games like Cash Cab or Carpool Karaoke. Would make the commutes more interesting :D
