Waymo One is now one. It's been one year since the self-driving taxi service opened for public (but still very limited) rides in a geofenced part of the Phoenix area. Its fleet of Chrysler Pacifica minivans and other autonomous vehicles just hit more than 100,000 rides. To celebrate, Waymo One is now on the App Store, available for download for any iPhone user. But to actually order and ride the robo-taxis in Arizona, you still have to get on a waitlist.

Last month, Waymo launched its first self-driving taxi service -- Waymo One -- in Phoenix, Arizona, but you would hardly know it by scrolling through your feed. We don't know how many people are using the Google offshoot's self-driving minivans (Waymo won't say), but the ones that are have been surprisingly mute on social media. One exception is Shawn Metz, a 30-year-old HR manager who lives in Chandler, Arizona. Since he was invited to use Waymo One in December, Metz has posted at least a dozen videos on Instagram and YouTube, documenting his experience using Waymo's self-driving minivans. He's become the hero of AV enthusiasts on Reddit for his willingness to answer questions and post unedited videos of his rides.

On the chilly October day the New York City subway opened in 1904, the marvel of engineering and grit was greeted with horns, steam sirens and stations overrun by thousands of revelers. "Fast Trains in Tubes," blared one headline. On Wednesday, 114 years later in sun-swept Arizona, the launch of the 21st-century equivalent came in a blog post and an email invitation. Google offshoot Waymo announced it is launching the nation's first commercial self-driving taxi service in this and other Phoenix suburbs. The 24/7 service, dubbed Waymo One, will let customers summon self-driving minivans by a smartphone app, a la Uber or Lyft. Waymo's move comes after nearly a decade of development, more than a billion dollars in investment, and 10 million miles of testing on public roads.

Waymo self-driving cars will be used to chauffeur "early riders" to and from their Walmart online grocery pickup location. Waymo self-driving cars will be used to chauffeur "early riders" to and from their Walmart online grocery pickup location. The future is here and soon it will be toting grocery shoppers around Phoenix. Walmart and Waymo -- formerly Google's self-driving car project -- announced on Wednesday the launch of a pilot program that will allow consumers to make their grocery pickups with the help of an autonomous vehicle. Participants in Waymo's "early riders" program will be able to take a driverless shuttle service to and from Walmart whenever they purchase groceries from Walmart.com using the retailer's online grocery pickup service.
