I feel the same way about about hubless wheels; people seem to design with them because they are “cool”, not because they are practical.
On another note I always have wondered how the tweel tires work in mud or snow? Does stuff just get jammed into all of those crevices and throw the whole thing off balance? When I had my Audi and Subaru I used to spend a lot of hours sliding around in the snow and mud, and when I got up to highway speeds I would notice real quick if there was any in the wheels. I can only imaging it being much worse with the Tweel.
