Those spiderman nets are just a way for drone pilots to stop themselves from flying the drones. When drone pilots know there are nets it just gets them worried about loosing their drone and so they just don’t fly it. Otherwise, it doesn’t have the capability to actually stop a drone. Those nets are not useful at all. Firstly, because the drone that’s throwing them must be fast enough to catch up with the other drone (usually it never happens, unless the second drone in flying in a circle or so). Secondly, if the second drone keeps flying higher and higher (or something like a sine wave) its impossible for the first drone’s pilot to throw the net and capture the second drone. Also the drone has only 1 shot at it, because it carries only 1 net. There are better ways to stop drone usage by setting up signal jammers I guess.
