If I were a billionaire, that would be the first thing I would have custom built. It probably wouldn't be that difficult. I would use a gas turbine electric generator with axial motors for each wheel, carbon fiber panels for the inside, aluminum and Kevlar for the outside panels, and a titanium frame.
Reminds me of the ATV from Mass Effect series, largely due to the elevated 6 wheel, "jumping spider" suspension system layout. Personally, I think your design is the prettier, more functional looking of the two, though. Good job!
Hey, I only got to drive one because my car got smashed and the rental place was out of other options. That said, there's a good reason the older generations called them "land boats" because you'd turn the wheel for twenty minutes just going through a drive thru. 😉😉😉
