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. The Arizona pilot comes after California’s Department of Motor Vehicles revoked the registrationof Uber’s 16 self-driving cars because the company refused to apply for the appropriate permits for testing autonomous cars.

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. The company first started allowing riders to take trips in its self-driving cars in Pittsburgh last September.
