Almost two months to the day after Uber loaded its fleet of self-driving SUVs into the trailer of a self-driving truck and stormed off to Arizona in a self-driving huff, the company is preparing to launch its second experiment (if you don't count the aborted San Francisco pilot) in autonomous ride-hailing. From a report on The Verge: What's different is that this time, Uber has the blessing from Arizona's top politician, Governor Doug Ducey, a Republican, who is expected to be "Rider Zero" on an autonomous trip along with Anthony Levandowski, VP of Uber's Advanced Technologies Group. [...] Starting today, residents of Tempe, Arizona, can hail a self-driving Volvo XC90 SUV on Uber's ride-sharing platform. All trips will include two Uber engineers in the front seats as safety drivers, in the event a human needs to take over control from the vehicle's software. Uber says it hopes to expand the coverage area to other cities in Arizona in the coming weeks.
