That's
kind of what I mean. Your very nice graphic shows only a 30 degree angle from the long axis of the car, but as I recall, the Hucho book picture showed the smoke flow toward the tire/wheel more like 60 degrees as measured from centerline. Maybe somebody here with Hucho can look it up and post it, as I last read that a year or so ago. In other words, the deflection was a LOT more than one might intuitively suspect. Until I saw it, I would have thought the air went more or less straight on back, with parallel bow waves and wakes around the front wheels. Perhaps the shock wave off the nose impacts the ground, creating some sort of curtain that the air moves laterally around. Best to do tuft tests on your car, see what angle the flow really is, then add rounded leading edge deflectors accordingly. Seems like I saw a pic of a baby Benz with such pigeon-toed deflectors.
And, the leading edge of the deflector should be radiused or rounded, like the leading edge of a wing.
