I don't understand the use of that picture. It seems pretty arbitrary to overlay it on a vehicle. The entire flow is affected by the front of the vehicle, which never matches the shape of an aerofoil. The overlay isn't an aerofoil to begin with-- the point of an aerofoil is to have a curved front that allows the wing to function at a range of attack angles.
