> How would the autonomous delivery trucks you are talking about actually deliver the packages? The very difficult part would be getting the packages from the vehicle to the person's door. It would not work if it required the customers to come outside to pick up the packages, people wouldn't be home, they might be busy at the moment, it would be difficult to ensure they don't take the wrong or someone elses packages. I've considered that before and I just can't figure out a way for that to work. Tightly specified mailboxes. Imagine that if you installed a special "UP-EX" mail box, you could receive packages securely when not at home. The truck has an arm that places the item directly into the receptacle.
