Autonomous car specialist Waymo has said it's expanding its robotaxi service in Los Angeles less than a year after launching there.

In another escalation of the robotaxi wars, Waymo opened up its driverless ride-hailing platform across more of Los Angeles, and is now offering rides around the clock from Santa Monica Pier to Downtown LA.

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.
