Nope, and now perhaps you can appreciate how hard it is to come up with solutions. Problems are easy to spot, your intuitions on solutions is often wrong. Thousands of drones are in use right now, this very day, serving useful purposes. Drones can already survive heavy wind and rain. Part of the reason is that open space is far less obstructed and much easier to navigate in an automated fashion than public roads. In comparison to drones, the number of non-experimental self-driving cars is probably close to zero. Self-driving cars also would have no flexibility in package placement, making the idea a non-starter. Amazon isn't going to leave your packages at the curb. One problem people seem to be having is that they think Amazon has to come up with a perfect solution that covers every edge case. They don't. They can start using drones for carefully defined environments and expand from there.
