Everyone here knows such a vehicle would produce the tremendous tornadic vortices of smoke in the rear of the vehicle that we see in this image. What's the point?

Why not use this wonderful tool he has to improve the machine?

I would be glad to ship him our 2015 Concept Vehicle 3D Printed model to test, if I was sure it wouldn't be rubble after the 7500 mile round trip.

I think he's using 1/18th-scale models which happen to available.And we have no idea what he's NOT showing us.
