Dropping into random pages in the
Random Aerodynamic Oddity of the Day Thread can be entertaining. I was looking for a reference to 4-bar linkages and found this instead:

One study conducted in 1989, “Turbulent Flow Separation Control,” explored controlling airflow—flow separation—to decrease energy expenditure and weight in airfoils, inlets, and diffusers and improve aircraft control and decrease drag. The study employed vortex generators, aerodynamic surfaces protruding from a body that draw faster moving air to the surface of the vehicle and disrupt the slower moving boundary layer air around a vehicle, the use of which can be traced back to research conducted by the National Advisory Committee for Aeronautics (NASA’s forebear) in the 1950s. The generated vortices “energize” the slower-moving boundary layer and thereby reduce drag and, in aircraft applications, increase lift.

Maybe you're not using enough of them?
(Also found this,
but that's another story:

I'd like to see that setup in a Model T center-door sedan.)
