Google robot postmen?

Google can track packages.  Google can put them on robot trucks and deliver them to your house without having a human driver.  The truck can come by the house again tirelessly until you are there to sign for the package.  The only thing Google doesn’t have yet is a picture of your face so it can be sure that you’re the one signing for the package.

Or does it?   It shouldn’t be too long before you see Gods (Google Delivery Services) Trucks outside your door.  What could be better than getting a message straight from God?
