I suspect they'll do the same as they do now for these automated drop-off/pick-up locations you get next to supermarkets etc.
The van would basically consist of set of mobile electronically secured lockers. Swipe/tap the card you paid for the items with, or us a an app etc. And the locker with your stuff in it unlocks. Take your items, close the door, and the van heads off to the next delivery.
The issue being things like access, or the size, weight, number of items
i.e. Having to leave the house/office to do the collection from the van yourself. Having to limit the weight/size, to make sure it's something you can actually pickup your self.
No good of course if your housebound etc.
Perhaps these new White 'Auto' Vans, could include a delivery drone in the back?
