Indeed Mr Musk,

the design may not work directly,

but if the goal is to gather data on what works,

eventually, something will be brought up.

That said,

3 person per wheel,

middle part contracting on road mode,

then on flight mode,

they congregate together in the middle.

technically, feasible.

but a necessary design?

absolutely useful?

probably not.

flight mode. 6 in the middle.

jumbo motorcycle mode. 3 per wheel.

and 4 wheel mode. 6 in the middle.
