Waymo robotaxis are now open to all users in San Francisco, expanding the self-driving ride-hailing service, which has been available in the city to a limited number of riders. In a blog post on Tuesday, Waymo said nearly 300,000 people have signed up for the service, called Waymo One, since the Alphabet-owned company opened its waitlist. The company began commercial passenger operations in August after a period of testing. | CNBC
