In the not too distant future. It will be something more akin to:
1) Fridge finds several items low and proceeds to order groceries.
2) Website schedules car to be driven to store.
3) Store Robot packs groceries and finds car in car-park.
4) Negotiation between Car and Robot occurs, groceries placed in trunk.
5) Car drives off home.
6) Car notifies domestic robot that groceries have arrived.
7) Groceries put into fridge by domestic robot.
8) Lazy human requests that domestic robot gets them a can of beer. Unaware that the whole process occurred.
