Not sure why people are fixating on autonomous drones. If this happens at all, the first drones will clearly be human controlled from the point they leave the warehouse to when they reach the delivery zone. They will be teleoperated and probably armed with a speaker and microphone so that the operator can speak to the recipient. There will be multiple cameras so if someone is interfering or trying to steal the payload, their face can be recorded so that they can be reported to the authorities. Unless there is extremely high winds or precipitation, weather doesn't have to be that huge a limiting factor either. Pointing out the problems of autonomous aerial navigation in this case is irrelevant.
