Anyone who can produce an "air car" for a reasonable price (say the

insentive to do so so I have to ask...If this is so easily achievable
with current technology...why hasn't someone done it ?


I daresay that anyone who could afford one of those could also afford
a real airplane and a real car, each which would outperform the
mechanical chimera, as well as the hanger space in which to park
on while using the other.
