Couldn't it be used to identify/track the ICE vehicles? Observe where drones suddenly become enclosed in a no-fly zone (do I understand correctly that operators get notification that they should land immediately)?
Not that a government that just pops up no-fly zones would care about your drone, but just saying.
I have my doubts. I would guess one "popping up" would at least be delayed such that it's pretty pointless by the time the drones are notified. Annoying indeed, useful (even to the ne'er-do-wells trying to enforce this crazy stuff) not so much.
