Even when only part of a system/process can be automated and it looks like the rest is too hard to automate, doesn't mean there wont be ways around it, or ways to cheat. Just look at how automation in factories has developed. Sometimes all it takes is to change the process slightly.

In the case of your delivery example, a person is not necessarily required to drop off the package. A system could be setup where you can request a delivery time frame for your package (e.g. between 7-9pm). When the autonomous delivery van arrives, it parks outside your house and notifies you of its arrival. You go down, scan your card and the van dispenses your package. The van then goes off to its next delivery.

Or the van has a minimum-wage person with no driving skills who just has to be able to find the right package and say, "Here you go! Thank you for using Zap Delivery!"
