Where's deliver bot?

Fed Ex is not making much money on the ground leg of delivery, delivering the last  mile.  The problem is he thousand pounds of enclosure needed to carry around the human driver.  Dump that, replace with a deliver arm that can drop a package inside a curbside enclosure.  The deliver bot becomes much more light weight, drives a bit slower and is a lot safer.  You keep one or two human monitors who mainly go out and rescue deliver bots from humans.

FedEx Corp. executives said retailers should be paying more for shipments to help offset the cost of expanding its network to meet the growing demands of e-commerce.
‘There’s an enormous interest in people having things delivered to themselves. It does not change, one iota, the input costs of the delivery,” Chief Executive Fred Smith said in an interview.
FedEx this year increased its capital spending to $4.8 billion, with the largest increase in its ground division which handles most of its e-commerce business, and intends to continue the increases in the next two years.
