Following allegations of injuries to pedestrians, officials are looking into about 600 self-driving cars manufactured by a division of General Motors.
"Encroaching on pedestrians" is how the National Highway Traffic Safety Administration (NHTSA) describes self-driving automobiles developed by Cruise.
According to the NHTSA, there have been two reports of injury to pedestrians.
According to Cruise, it "continues to outperform comparable human drivers" in terms of safety.
The reports, according to the NHTSA's Office of Defects Investigation, included autonomous vehicles colliding with pedestrians at pedestrian crossings in San Francisco.
On one August 2023 incident, the self-driving auto struck an individual at a speed of 1.4 mph.
In the other incident, a pedestrian was crossing the road when a car driven by a person struck it, knocking the pedestrian in front of the driverless vehicle.
The autonomous vehicle allegedly "braked aggressively" in the October 2023 incident, but it was unable to stop in time and collided with the pedestrian.
The NHTSA further stated that it was investigating two online-posted films that featured pedestrians.
The California government decided in August to approve Waymo and Cruise, two taxi companies, to operate a driverless car service that is available around-the-clock.
They had previously been limited to providing paid rides at night.
In San Francisco, there was debate over the decision. Some claimed the autonomous cars were safer than those operated by human drivers, while others claimed they posed a risk to public safety since they blocked fire trucks.
