I wonder if there are magic QR codes (other barcode types available) that the car can read and follow, e.g. if they drive into Waymo's cavern and the Internet connection isn't solid. GoPro's "Labs" has a special firmware for their cameras, and the configuration doesn't happen by selecting items on the tiny screen, but on a webpage that generates a QR code that can then be entered into the GoPro by pointing it to the generated QR code.
