Uber’s autonomous trucks are now doing actual work for customers via Uber Freight, Uber’s commercial cargo shipping on-demand app. The first runs are being done in Arizona, with regular hauls operating with both human drivers and autonomous trucks working in tandem.
How it works is that Uber will load up the freight on a conventional, human driven truck who collects the load from the shipper and then does a short haul run to a transfer hub. The short haul truck then loads its cargo onto a long-haul freight transport, which is autonomous for the purposes of these trips. That self-driving test truck handles the highway driving for the longer portion of the trip, handing it off once again to a human-driven trip for the short haul cap to the overall journey.
