I love this idea with a motorcycle! You're already out in the open/cabin and you could just drive it in and others could ride with you, or you could use just to get out of the rain. Lots of larger bikes have more than enough engine to pull this off. Brakes could be electric and run by a pigtail off the bike (might have to use regen braking also to power all the extras built into the outer shell). How would you steer? This is the only thing I can't figure out.
