Kinda, but not really. In Germany you can do that on public roads. And there are many circuits you can do track days at that only require a street legal car and a helmet.
Meanwhile even the suction functionality of the roadster will probably be banned at most track days because it throws a bunch of rocks and dirt at cars behind you.
Tyres also throw stones and dirt at cars behind, sometimes with remarkable force. But you're right, road debris is a serious question here. I can only imagine that this is so obvious that it cannot have been overlooked.
Surely the intake will need to be minimally filtered, my guess is something similar to fly screen mesh (screen door material, for the yanks) or finer. Debris would then just fall to the ground when the fans aren’t running.
