Waymo continued its eastward march this week, rolling out its robotaxi service in Atlanta under the Uber app. With this debut, Atlanta became the easternmost city where Waymo has launched operations.

The launch, if successful, is poised to propel the businesses of both companies. Uber, which has locked in partnerships with 18 autonomous vehicles companies, said it has an annual run rate of 1.5 million mobility and delivery AV trips on its network.

Uber Technologies on Tuesday is beginning autonomous ride-hailing in Atlanta with Alphabet unit Waymo after offering the service in Austin, Texas, since March.
