I don't know what to tell you. The subpoena system has been around for a VERY long time before Google even existed. You seem to be unfamiliar with it so I'd encourage you to read up before you call it a "formality."
This is not some newfangled shiny thing. If you hold records that are important to a court case you can be forced to give them up by court order. This is true regardless of who "you" happens to be. If police "have access" to a Waymo, it's only because they also "have access" to your phone, your medical records, your car rental history, etc., etc.
