Alphabet's Waymo is starting to commercialize self-driving car rides in Arizona by offering an Uber-like service that works over a mobile app.

The company launched Waymo One, which will first be available to select riders in the Phoenix metro area before a potential wider rollout across the community. Consumers will download an app that functions like Uber or Lyft; confirm your pickup location, input where you want to go, and finally receive a price estimate before you formally request the ride.

If you have a question during the trip, open the app to connect with a Waymo support agent. The self-driving vehicle also comes with in-car consoles that connect with rider support.

"These channels will become even more important as we transition to fully driverless rides," Waymo said. At the end of the ride, Waymo's app will also ask you to rate how well the trip went, on a scale of one to five stars. Self-driving rides through Waymo One will be available 24 hours a day, 7 days a week.
