There is already a solution out there and it works. Japan has something called Takyubin-box. Delivery person arrives at door, nobody home, opens box, puts in package, sets a pincode, puts pincode in person's mailbox, person comes home, retrieves packages. Some T-boxes are enabled with fancy features, some have simple tumbler locks with manual one-time code setting. I can't believe Bezos and company can't take that concept and retool for the US market.
