In June 2022, nearly twenty Cruise driverless cars stood still and blocked traffic for two hours on a street in central San Francisco, USA, causing tailbacks, making the area impassable and inhibiting night street-sweeping.

The cars were reputedly disabled after they had lost touch with a Cruise server. The incident was resolved when the cars were manually moved out of the way by Cruise employees.

Per WIRED, a Cruise employee later sent an anonymous letter to the California Public Utilities Commission, claiming that Cruise loses communication with the automated vehicles 'with regularity', blocking traffic and potentially hindering emergency vehicles.

In April 2022, Twitter users posted videos of a Cruise vehicle moving away from San Francisco police after they had tried to find put whether the car had a driver.
