Walmart in collaboration with Zipline is testing drone delivery in Arkansas.  Zipline technology includes a platform located adjacent to a store with drones and their operators trained to manage aerial delivery over a 50-mile radius.

It is evident that delivery weight is a restraint, and the service will probably be used for medical necessities, prescriptions and small urgently required personal care products especially in remote locations and during inclement weather.

Based on improvements in technology it is evident that drone delivery will serve as an adjunct to delivery using conventional vehicles including autonomous EVs.  Correctly implemented, technologies such as drone delivery will ultimately find applications and provide benefits to both retailers and consumers.
