Analysis of Factors Contributing to GM Cruise Accident in San Francisco

A recent report released by GM highlights some of the key factors that contributed to the October 2, 2023, accident involving a GM Cruise autonomous vehicle and a pedestrian in San Francisco. While it is reassuring that the pedestrian survived the incident, the report sheds light on the serious flaws in the vehicle’s response and the underlying issues within the automated vehicle industry.

GM Cruise had been operating autonomous vehicles without human safety drivers in California since 2021. By 2022, they had a fleet of 100 robotaxis operating in San Francisco, which expanded to 300 once they received approval for night operations. While previous incidents had occurred, none were as severe as the one that took place on October 2.

The report provides a detailed timeline of the events leading up to the accident. After the initial impact between a human-driven Nissan and the pedestrian, the Cruise AV reacted by undertaking a pullover maneuver to pull over from the road. However, tragedy struck when the pedestrian, trapped under the vehicle, was dragged about 20 feet, exacerbating their injuries.

One alarming revelation from the report is that the automated vehicle failed to transmit crucial footage of the pullover maneuver and the pedestrian dragging to the relevant parties. This raises concerns about transparency and the potential attempts to hide crucial information regarding the incident.

Additionally, the report highlights a technical issue with the Cruise AV’s wheel speed sensor, which detected an imbalance among the wheels. This imbalance caused the system to shut down prematurely, preventing the vehicle from effectively executing the pullover maneuver as programmed. Furthermore, the lidar sensing systems failed to provide consistent detections of the pedestrian, resulting in the collision detection system incorrectly identifying the location of the pedestrian as being on the side of the AV rather than in front.

These revelations expose significant flaws in the technology and systems deployed by GM Cruise and serve as a reminder of the challenges faced by the automated vehicle industry. Addressing these flaws and ensuring the safety of pedestrians and passengers should be a top priority for all companies operating autonomous vehicles. The incident serves as a valuable lesson for the industry to reevaluate safety measures, improve technological capabilities, and prioritize transparency and accountability.

While the future of autonomous vehicles holds immense promise, incidents like the one involving GM Cruise underscore the importance of thorough testing, continuous monitoring, and stringent regulations to ensure the safe deployment of self-driving technology. Only by learning from these incidents and working together can the industry progress toward a safer and more reliable future for autonomous vehicles.
