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.

The move is a key step by the company to begin carrying paying customers while its traditional car-selling business falters.
