Day one? Maybe, maybe not. It's more so the first day that the seasoned early test riders are free to take pictures and videos of their experiences, so get ready for them. Moreover, it's not day one for the driverless Taxi service without drivers, for the safety drivers are still there until they aren't. Day one would have been waymo fun if the cars went full monty driverless.
"Under the early rider program, Waymo required participants to sign non-disclosure agreements. Those restrictions will be lifted for customers who use Waymo One, allowing them to take pictures and videos and to share the information on social media. In the coming weeks we're going to learn a lot about how Waymo's technology works—and doesn't work—in the real world."
