The Darwin effect has been in place for those drones for a whle now.

A report two or three weeks ago (if I haven't lost track of the time) indicated one "drone flyer" lost control of his drone in a public park, and decapitated himself (with the usual fatal result).

(Damage to the drone was not reported in the stories I saw, but it's probably on eBay now - "only flown once"(?).)
