What luck? Seeing the link did not impress me. A free magazine subscription is hardly a worthy prize for the effort put into getting that winning shot. I get more substantial prizes at National Coney Island...
The Star Wars Episode 2 I think had multi-level lane for various flying craft. I guess we'll have to wait until the 24th Century to find out if that will be the norm.
Another good idea is deploying the drone from the roof of your car to search out why traffic is so slow and perhaps an escape route is possible. Then, it would return to the roof of your car to recharge for the next deployment.
I would think that in heavily trafficked areas the drone would fly at an altitude say 'streetlight high' That way it would be a good spy and not subject to attack like possible at the street level flying.
One question I have, How do you control the gimbol's movement while operating the quad from the controller? It would seem impossible unless you have a third control on the controller just for the gimbol.
