I'd like to think that we could either use OBD data or ABS speed sensor frequency to determine speed. A lookup table would provide the threshold values and outputs. A basic stepper motor control would manage spoiler attack angle.
If you could "pitch out" at low speeds and in eco-mode, then you could install a monster wing without hurting highway mpg. Similar control could be done on active grille shutters or front aero.

As EarlQ pointed out, Aeromotions has 3 active aero applications that differ by either actuation type (internal/external) or single element vs. split element. We just did a BRZ fitment with our "static" wing which can be seen here:

This static fitment can be upgraded to active as well using our external R.Module.
We've also built the active front splitter that you are referring to. We did extensive CFD testing on it, then took it to the WindShear 180mph rolling road wind tunnel where the Nissan Delta Wing was tested. We have some info on it here:

We do implement a Drag Reduction System (DRS) like F1, so that there isn't much of a drag penalty.
One thing to note on our BRZ testing: our airfoil is very unique (even though it looks very basic), and implements a concave pressure recovery system which seems to have a huge benefit with the BRZ shape (the window rake + factory deckled specifically). In static mode, we only need 2 degrees of angle of attack (AoA) to achieve perfect balance. And because of our low drag shape and only needing 2 degrees of AoA, there isn't much of a drag/speed penalty.
