I was barreling down the interstate, the only car on the road late that night. Suddenly my car brightens up everywhere, with colored lights dancing and flickering about it. A vehicle drops from above to nearly the same level as my door's rearview mirror right outside.

 

"Pull over."

 

Wtf? When did they get hover cars? (Just a note: this would be unnerving even in a future where it's thoroughly established. Your own car roof blocks the view of what's happening above, for one thing. Even with a sunroof, the dazzling lights would just mess up your view) Oh boy, I pulled to the side.

 

No ticket, but got a friendly warning on a slip of paper. I drove off again, half-barreling now at a smoother pace.

 

(And not much later)...Did that even happen?

 

Then I saw it, and everything made sense. White lettering on a dark gray background: "Speed Limit Enforced by Aircraft"

Yeah, the aircraft doesn't actually pull you over, they just radio a cop.

Well now, that's just a written explanation (and simply untrue at that).

 

So as is hopefully obvious, a picture speaks nearly a thousand more words...
