Waymo’s robotaxis will begin carrying passengers through parts of Atlanta Tuesday in an expansion of a partnership with Uber’s ride-hailing service that began earlier this year in Austin.

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 and Waymo are expanding their partnership to Atlanta, where your next ride could be an autonomous Jaguar I-Pace. Not into that? You'll have the chance to switch to a human driver.
