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.

Waymo closed a $5.6 billion funding round in October to expand its robotaxi service across the U.S. The autonomous vehicle venture is owned by Google parent Alphabet, which led the series C investment in Waymo, alongside earlier backers including Andreessen Horowitz, Fidelity, Perry Creek, Silver Lake, Tiger Global and T. Rowe Price.

Alphabet's Waymo said on Tuesday its autonomous ride-hailing service, Waymo One, is now available to everyone in Los Angeles, a sign of rapid growth and adoption of the technology.

Waymo was already operating citywide in Phoenix, Arizona and San Francisco, California.

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.

The expansion comes eight months after Waymo began offering rides in Los Angeles to a limited group of passengers chosen from a waiting list that had ballooned to more than 300,000 people.

Waymo in Los Angeles is now open to everyone - without a waitlist or invitation code. Sen. Elizabeth Warren (D-Mass.) said Monday that President elect-Trump “and his transition team are already breaking” a law on presidential transition.
