The Cruise vehicles blocked a bus lane and held up traffic at the busy intersection of Sacramento and Leavenworth in the city’s posh Nob Hill neighborhood. Around the same time and mere blocks away, a Cruise vehicle was also blocking Sacramento Street near Mason Street Another blocked an intersection in the Cathedral Hill neighborhood.

San Francisco has turned into a sort of unofficial testing ground for self-driving vehicles.

San Francisco has touted itself as a tech hub, but performing a city-wide experiment is not without its risks. A Cruise vehicle hit a Toyota Prius back in June, and in May, to the which raised concerns about the company’s dedication to safety.

California has allowed passengers to ride in driverless Cruise vehicles are operating using beta testers in a small section of the city and are only available during certain times of day and under perfect weather conditions.
