Just to spell out the scientifically obvious: any energy you take from the air or passing pavement to charge while driving comes from the car, along with extra losses from friction, heat, etc. So unless it's a very large, very streamlined solar array, the OP's scenario remains impossible. Charging while braking, however, is already a reality.
