Two Cruise driverless taxis blocked an ambulance carrying a critically injured patient who later died at a hospital, a San Francisco Fire Department report said, in another incident involving self-driving cars in the city.

On Aug. 14, two Cruise autonomous vehicles were stopped in the right two lanes of a four-lane, one-way street in the SoMa neighborhood, where the victim was found, according to the department report. It said that a police vehicle in another lane had to be moved in order for the ambulance to leave.
