AEB technology works through an integration of forward-facing cameras and sensors that automatically activate the brakes when a potential collision is detected. According to AAA’s latest findings, newer versions of AEB systems exhibit a marked improvement in their effectiveness at preventing forward collisions. During their testing, AAA employed a controlled private course to evaluate three vehicle models—Jeep Cherokee, Nissan Rogue, and Subaru Outback—across two categories: vehicles from 2017-2018 and the latest models from 2024.

The AAA study tested these vehicles at various speeds—12 mph, 25 mph, and 35 mph—and utilized a staged dummy vehicle in the roadway to assess AEB’s capabilities. Astonishingly, the results showed that all 2024 model vehicles activated the brakes in time to prevent a collision, representing a stark contrast to the older models, where only 51 percent succeeded in the same scenarios. This new data demonstrates a clear performance enhancement in AEB technology, especially when compared to AAA’s previous tests in 2022, which revealed lower efficacy rates at higher speeds.

Greg Brannon, AAA’s director of automotive engineering research, acknowledged the progress made in AEB technology since testing began in 2014, but he also tempered expectations regarding its current limitations. While current systems are adept at preventing forward collisions, previous studies conducted by AAA have indicated that AEB technology still falls short in preventing other types of accidents, such as T-bone collisions or left turns where vehicles might encounter oncoming traffic.

The push for enhanced automotive safety features is set to gain vigor in the coming years, particularly as the National Highway Traffic Safety Administration (NHTSA) has finalized a requirement for a more rigorous AEB system in all new light-duty vehicles by 2029. Presently, approximately 90 percent of vehicles on the road are equipped with standard AEB; however, the new regulations emphasize the necessity for systems capable of at higher speeds and with the ability to recognize vulnerable road users like cyclists and pedestrians, day and night.

Despite the optimism surrounding these advancements, some automotive manufacturers have voiced concerns regarding the feasibility of meeting the upcoming requirements. The Alliance for Automotive Innovation, an industry group representing major car manufacturers, articulated its apprehensions in a letter to the NHTSA, claiming that the newly established AEB mandate may be “practically impossible” to implement with currently available technology. This resistance indicates potential complications that could delay the integration of the enhanced AEB systems intended to bolster road safety.

As the automotive industry continues to evolve, the AAA study serves as a reminder of the promise inherent in technological advancement while also reflecting on the challenges that remain. With AEB technology playing a crucial role in enhancing vehicular safety, the upcoming years will be pivotal in determining how effectively these systems can adapt and improve in response to the growing demands for road safety and innovation.

The Office of Defects Investigation (ODI) has pinpointed these incidents, collectively involving vehicles equipped with FSD, after entering areas with compromised visibility due to factors such as sun glare, fog, or airborne dust. One particularly alarming crash resulted in a fatality, while another led to serious injury. The NHTSA’s investigation is especially focusing on various Tesla models, including the 2016-2024 Model S and Model X, 2017-2024 Model 3, 2020-2024 Model Y, and the 2023-2024 Cybertruck.

The NHTSA’s review will evaluate multiple aspects of the FSD system: the engineering controls’ effectiveness in detecting and appropriately responding to visibility limitations, any other similar FSD-related crashes occurring under identical conditions, and the nature of updates or modifications Tesla may have implemented regarding FSD’s performance in low visibility scenarios.

With the backdrop of these investigations, the agency will delve into the timing, purpose, and capabilities of any enhancements made to the FSD system, putting Tesla’s proactive assessment of safety impacts under scrutiny. This close examination follows Tesla’s announcement of a new driverless Cybercab robotaxi vehicle, amplifying the stakes involved in the ongoing discourse around autonomous driving technology.

In the wider realm of autonomous vehicle technology, Tesla CEO Elon Musk has been vocal about his preference for a camera-based computer vision approach for self-driving systems, claiming sensor-based alternatives are heading towards failure. This assertion stands in striking contrast to the strategies adopted by competing robotaxi companies like Waymo, which relies on a combination of sensors, including lidar and radar, alongside cameras in their self-driving vehicles. Other automakers are also incorporating lidar and radar into their driver assistance systems, fueling a debate about the best technologies for achieving safe and reliable autonomous driving.

As Tesla continues to push the boundaries of technology with its FSD features, the implications of this NHTSA investigation could shape the future of autonomous vehicles and raise critical questions about safety standards and regulatory frameworks. The outcome could have far-reaching effects not only for Tesla but for the entire industry, reinforcing the importance of thorough evaluations and responsible deployment of autonomous driving systems.
