You missed the bit where the thing stops working if it causes the vehicle to accelerate.

What it would do (in defiance of the Principle of Equivalence) is to support the car at any altitude in a 2,000-g gravity field. Hence my suggestion that what this gadget replaces is wings and rotors. (And wheels, and air fusions, and jacks.)
