You can't divert the air and decrease drag. Drag is a result of making the air move that was previously sitting still. Anything you do to add energy to the air will require that you add energy from you vehicle.....the air does not just move itself. I think too often we get caught up in the concept that air is moving over our vehicles....our vehicles move through the air. Subtle but VERY significant difference.
