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 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.
