But overall, whether it works or not.
It does actually make much more sense now Mr Musk.
As for when the wheels converge into motorcycle mode
from the flight, if will "skid' from the ground,
affecting the tires,
I think there can be another small wheel sets that
can descend to converge them in safety.
As the flight mode would also have smaller sets of wheels
that can be used as a car, standing vertically,
unaffected by the turbines. There should be room/space for this.
