I think you are really understating it. I believe Chandler, AZ has been Waymo's proving grounds for years, and according to this article (https://www.wsj.com/us-news/waymo-phoenix-arizona-self-drivi...) the Phoenix area is the leader of autonomous vehicle service.
I mean it’s been like that in SF for a while now. Tons of people take Uber/Lyft still but I see dozens of Waymos everyday and I’ve been Waymo only for about a year now.
It’s just absolutely normalized here to the point of barely being a novelty anymore. Waymos are absolutely everywhere.
