there is absolutely no way that that thing is remotely controlled. its automated.
I think a quick, simple, more badass, albeit not very realistic solution to the strealing problem is to just parachute the package down
Would be cooler, but then you have a definite problem of wind and whatnot moving the product off course, or it falling down a chimney (which could kill people) or landing in a tree or a river or something.
And in response to the worry of it being shot down or stolen, then it's a criminal activity.
The machine is definitely robotic, but it's going to constantly be sending back information to it's depot, including live video, just like any drone.
And if it's shot down and notices it (it probably will, as it will likely have 360 degree panoramic view for it to safely notice and fly around obstacles), then Amazon will be able to press charges against whoever has attacked the product.
And you'll be severely punished for stealing high-tech equipment, packages, and much more so for firing a gun at an aerial vehicle.
