Although I expect that the NHTSA will nix it because of the high pressure tank that would go boom if there were an accident.
Doubt it, they allow CNG and LPG tanks. Those not only go boom but tend to create a mushroom cloud when they go boom. One thing I like about this car is the range is reasonable, the fill time is quick and most service stations (not “gas stations”) already have compressed air systems with a hose outside to fill with.
An air system designed to inflate tires is NOT going to be able to fuel up this vehicle. It is going to require far more pressure than tires require.

That car requires 350 bars of pressure or over 5,000 psi.
