These used to be called radio controlled helicopters...
Again, now that the yuppies have heard of them, everything changed. It's a fucking "drone" now. It's a damned toy helicopter, and they've been around for ages. People have been mounting cameras on them for ages.
All this drone talk is annoying.
As for that particular radio controlled toy helicopter, I can't imagine what you could possibly see within it's very limited range of operation that wouldn't be blatantly obvious from the driver seat.
There's also no fucking way those would ever be let on the roads.
