Tesla is taking steps to launch a ride-sharing service that could compete directly with Uber, Lyft and Waymo. Why it matters: Tesla has long pledged to run an autonomous vehicle network, which could become a significant new source of revenue at a time when its sales have flattened.

The Alphabet unit starts commercial operations in its fourth city, where rides can be booked with Uber’s app. Uber is also providing charging and maintenance services.

Uber and Lyft are both planning to deploy autonomous taxis in the U.S. this year. Uber has partnered with Waymo to deploy its self-driving Jaguar I-Pace EVs in Austin first and then in Atlanta later this year. Lyft has partnered with start-up May Mobility, AV technology company Mobileye and dashcam firm Nexar to deploy robotaxis in Atlanta.
