Amazon details its plan for how drones can fly safely over U.S. skies
I still don't understand how an autonomous delivery drone is better than an autonomous delivery car.I feel like a delivery drone is the absolute most complicated way to solve this problem other than somehow involving rockets.Drone limitations:
- Needs great weather.  
- Package size and weight exceptionally confined.
- Exceptionally limited range.
- How to actually get package from drone to human?  Drop?
- Night flight? Yes / no?  Probably not.Car limitations:
- Traffic.
