That's really not the case. Aerodynamic drag starts to become significant at the point where it requires more power to overcome the aero drag than it does to overcome the mechanical drag. There's not a lot of mechanical drag in your car, so I'd say the aero starts to land on the heavy side of the equation at just 20mph - less for some cars, more for others.

Lead or follow. Either is fine.
