The Amazon-owned autonomous vehicle developer announced that it would soon start mapping and gathering data in Atlanta, where it hopes to eventually launch a robotaxi service. That means that Zoox will be testing in a total of seven cities, including Las Vegas, San Francisco, Miami, Seattle, LA, and Austin. The company said it would start accepting public riders in Las Vegas and SF later this year. The announcement came a day after Uber said it was preparing to launch its next partnership with Waymo in Atlanta.
