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.
