Uber announced today that its self-driving trucks have been operating in Arizona for the last couple of months. The company said it has two main transfer hubs in Sanders and Topock, but other than that, Uber is being pretty tight-lipped about the operation. For instance, it hasn't shared how many trucks are in use, how many miles they've driven, what they're shipping or how often drivers have to take over for the autonomous system, and has only said that the trucks have completed thousands of rides to date.
You can check out how the system works in the video below. The idea is that a regular semi will pick up a delivery load from a shipper and drive it to a transfer hub. There, one of Uber's self-driving trucks, and a safety driver, will take the trailer and transport it over the longest leg of the trip. Once the truck nears the delivery destination, it will again head to a transfer hub where a conventional truck and driver will pick up the trailer and take it to its final stopping point. Shipment details are handled by Uber Freight -- the app the company launched last May that connects shippers and truck drivers.
