I have visions of the air being as crowded and crazy as the traffic on the streets when I think too much about it. 😜 I think there are definitely some benefits to having unmanned crafts (no road rage or distracted "flying"), but have plenty of reservations, too. It will be interesting to see just how quickly all of this starts happening now that they have the technology to do it.
It seems to be moving at a fairly quick pace. Uber and Dubai look to be the biggest drovers of the passenger drones, and Amazon is really pouring money into getting their delivery drone service operational. If Uber are correct, they might be running trials with 5 years.
