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.

Waymo robotaxis are now available exclusively on the Uber app in Atlanta. It’s the second city after Austin host the companies’ burgeoning partnership.

If you want to boost your chances of being paired with a Waymo vehicle, you can opt in by going to the Uber app, tapping Account > Settings > Autonomous vehicles (under Ride Preferences), and then hitting the toggle next to Get more Waymo rides.
