It's really weird to me that Wal-Mart and other major B2B shippers haven't (at least visibly) been pushing regulators to allow for driverless cars/trucks. It's a little tricky to deliver pizza to my house when there's no guy to jump out of the car and make the actual exchange at my doorstep, but hauling stuff from a distribution center to a Wal-Mart that has staff on-hand to receive the merchandise? They should be upgrading their fleets _now_, and telling legislatures to remove any existing restrictions.<p>What happened to ruthless efficiency and abuse of excessive power? Wal-Mart forced suppliers to use barcodes and RFID tags. They forced video makers to shrink their packaging. Force us to accept self-driving cars already.
