It was a joke.

Since the plate has a single degree of movement, the sides could ride up into slots in the boattail or be made in overlapping halves. No need for a flexible cover.

Forget the self-optimizing behavior, make it stout and require 25% of the vehicle (rear axle) weight to move it. That should dampen the aerodynamic oscillations.
