The San Bruno Police Department wrote in now viral weekend social media posts that officers were conducting a DUI operation early Saturday morning when a self-driving Waymo made the illegal turn in front of them. Officers contacted Waymo to report what they called a “glitch,” and in the post, they said they hope reprogramming will deter more illegal moves. But San Bruno Sgt. Waymos currently operate in Phoenix, Los Angeles and San Francisco and in areas south of the city, including the suburb of San Bruno. “It blew up a lot bigger than we thought,” Smithmatungol said of the viral post to The Associated Press on Tuesday.
