California's self-driving car rules are essentially what Google asked for. Google/Waymo is fine with that; they have had lots of self driving cars running around Mountain View for years. The main California requirements are that the manufacturer takes total financial responsibility, has to file accident and disconnect reports, and can't use the technology commercially under a test license. Uber violated that last condition in San Francisco, and CA DMV revoked their vehicle licenses.

So Uber moved to Arizona, where they could kill more freely.
