Self-driving cars are another hallmark of the city's tech scene. Uber, Cruise and Alphabet's Waymo have all tested autonomous vehicles in the city. The infrastructure in Phoenix, with its gridded streets and consistent weather, made it an "optimal" place to roll these out, according to Bain's Hoecker.
Arizona's policy has been welcoming to self-driving technology. Former Arizona Governor Doug Ducey enacted several executive orders to reduce barriers for autonomous testing. Waymo began testing in Phoenix in 2017 and is the biggest player in the market. The company's robotaxi service now operates across 315 square miles in the city.
