obviously the speed you would move in a non-aero large car would be very slow but it still has a break even point.

No, the way wind turbine works
prevents them from having a break even point - they convert wind force (i.e. drag) to electricity at less than 100% efficiency. Therefore they will always produce less propulsion than drag.
