They saw the value of the Mini brand and didn't want to put a BMW badge on a lower end car, so they held onto it when they jetisoned the rest of the Rover group. The RR brand is selling to different customers than the BMW brand is. But I don't see that BMW would need the Tesla brand, there's too much overlap there IMO.
