Well, even crossing a highway with a large number of drones, is bound to lead to some of them failing and falling down into traffic? I suppose in some way there's some safety margin, having the drone do a controlled crash as soon as one engine fails -- but there must be scenarios in which the (presumably rather cheap) devices suffer sudden failure (eg: battery pack failure?).
