They'd choose a speed which gave the critical Reynolds number,to ensure a turbulent boundary layer.And 20-mph would have been adequate.
They're not cheating.This is the way the air behaves.And they are exposing the rear separation,where all the drag is.They are NOT injecting the smoke into the wake,so,in this respect they are avoiding the most unflattering aspect of the Beetle's flow.Here's another view.Forebody flow is fine
These are the money-shots!
