Zoox recuerda los autos sin conductor porque pueden no detectar el humo

Zoox, the self-driving car unit of Amazon.com, announced a recall of its fleet of 105 autonomous vehicles due to potential failures in detecting heavy smoke, which could hinder emergency response efforts. The recall was disclosed on Friday, July 17, following an incident on June 20 where an unoccupied Zoox vehicle encountered thick smoke obscuring an active fire scene. The vehicle entered the area, attempted to maneuver away, and ultimately came to a stop. After being remotely guided, it reversed, prompting first responders to place traffic cones at the site, effectively blocking two of the three lanes. The incident highlights broader concerns regarding the interaction between autonomous vehicles and emergency services. According to Jonathan Morrison, head of the U.S. vehicle regulatory agency, the National Highway Traffic Safety Administration (NHTSA) has identified a recurring issue with driverless vehicles obstructing emergency operations. In a letter to automated vehicle (AV) companies, Morrison noted that NHTSA has documented numerous cases where robotaxis have driven into active emergency scenes, blocked paths for ambulances and firefighters, or failed to respond to basic safety signals such as flashing lights, flares, smoke, fire, and traffic cones. In addition to Zoox’s case, local media in Texas reported an incident involving a Waymo self-driving vehicle in Dallas during late May. The vehicle partially blocked a route that fire trucks needed to access an apartment building on fire. Other video footage has shown Waymo vehicles obstructing ambulance pathways and entering active police scenes. These incidents have prompted both NHTSA and the National Transportation Safety Board to investigate separate cases involving Waymo vehicles, including one where a vehicle passed a stopped school bus with its lights activated, violating Texas state law. The Zoox recall includes a software update designed to improve the detection and response capabilities of its vehicles to heavy smoke scenarios. This update aims to enhance the system's ability to identify and react appropriately to environmental hazards that might otherwise interfere with emergency operations. The company emphasized that this enhancement is part of ongoing efforts to ensure safer interactions between autonomous vehicles and first responders. The NHTSA plans to hold meetings with vehicle developers by the end of the month to discuss potential solutions for these issues. A key concern expressed in the agency’s letter was that an autonomous vehicle unable to safely interact with first responders poses a risk to public safety. The agency stressed the importance of addressing these challenges promptly to prevent further incidents that could endanger both emergency personnel and the general public. As investigations continue, the focus remains on improving the safety protocols of autonomous vehicles to better accommodate and respond to emergency situations. With multiple incidents reported across different manufacturers, there is growing pressure on the industry to refine technologies that allow for more reliable and safe interactions with emergency services. The outcomes of upcoming discussions with developers may shape future regulations and technological advancements in the field of autonomous transportation.
