Angelenos can hail a robotaxi with the Waymo One app starting Tuesday. There are about 100 taxis in the Los Angeles fleet — but they don't drive freeways.

Waymo One, the driverless ride-hailing app, is now fully available to much of greater Los Angeles after the robotaxi service previously started offering rides in LA to a limited number of people on a waiting list.

Waymo on Tuesday opened its robotaxi service to anyone who wants a ride around Los Angeles, marking another milestone in the evolution of self-driving car technology since the company began as a secret project at Google 15 years ago.
