Based on ODI’s analysis of immobilization data, the potential safety risk is heavily dependent on the context of the immobilized vehicle’s location, detectability of the vehicle due to hazard lights automatically engaging, and none of the immobilization incidents reviewed resulted in a crash or injuries.
ODI also analyzed hard braking data which included 7,632 hard braking events commanded by the Cruise ADS. These events were determined by certain thresholds, including rate of deceleration, without regard to the appropriateness of the braking. ODI determined that Cruise vehicles contributed to 10 crashes that were reported under the Standing General Order 2021-01 (SGO), 4 of which involved a vulnerable road user and resulted in injury
