During development of their PNGV Car,GM noticed during windtunnel evaluations,that the windshield wiper had virtually no impact on drag.-------- I eliminated the wipers on my CRX at Bonneville and it had no effect on top speed.It's possible that the high-pressure bubble just ahead of the windshield "shields" the wipers from the outer flow.
