When I was a kid we always had to patch the inner-tubes on our banana seat bicycles, and started with turning our bikes upside down to do the change out.
Cannot do that with a car, would need a lift and do it from the underside.
One could design it so that when you cut/turn the wheels sharply they can be removed. From the website, looks like 4-wheel steering and 90 degree wheel turn access is incorporated. Perhaps these unique features could be used to address such concerns with a telescoping shock motorcycle suspensions.
A very simple explanation below of unsprung and sprung mass, nothing fancy.
