@ClaySpears In Israel is difficult. The railways are already almost overloaded, and they don’t communicate well the industrial areas, they are used mostly for person transportation. And it is difficult to build more, think in a small and overpopulated country. The only way for most relevant areas is or do the new railways through populated areas (including demolition of houses), or through ecologically sensitive areas.
I don’t see those drones good for transportation in the cities, but they can help in the transportation of ware and hardware between the industrial areas.
