Might be cool if you wired it to the brake pedal so that when you hit the brakes it would rise up and provide some resistance, or mayne tried to plant the rear end during brake dive. Of course after a few hundred of those the motors will burn out.
I doubt you would ever see speeds to make it usable anyway. Most spoilers do nothing under 80MPH or so.
