I actually wondered if I had this right and went and looked at the
Aerodynamics of Road Vehicles (5th ed). It says in summary:
"A complete investigation of the flow around the windshield of a real car and its surroundings still does not exist..." (Page 273)
What it
does say about reducing A pillar drag is all about smoothing airflow around the pillar ie making it as a large a radius as possible to prevent separation. Any material on 'steps' etc is about preventing water flow from the windscreen onto the side glass.
