Not sure I understand. That is just a standard R1S prototype that is now being produced and deliveries in small numbers start in a couple of weeks. Not some new or unknown prototype. Probably someone from corporate roadtripping in it before it is recycled since it is no longer needed as test prototype. Here is a production R1S parked next to an R1T.
Also while I love the R1T I don't care for the R1S. However they ARE produced off the same platform and share many common parts, specs and features.
