Automaker Group Sues to Block U.S. Rule Mandating Advanced Emergency Braking in All New Vehicles by 2029

A major group representing automakers has filed a lawsuit to challenge a landmark regulation introduced by the Biden administration, which mandates nearly all new cars and trucks to be equipped with advanced automatic emergency braking (AEB) systems by 2029. The regulation, finalized by the National Highway Traffic Safety Administration (NHTSA) in April 2024, aims to improve road safety by preventing collisions and reducing fatalities. However, automakers argue that the rule is unrealistic and unachievable with current technology.

AEB Technology at the Heart of the Debate

The Alliance for Automotive Innovation, a trade association representing major automotive brands such as General Motors (GM), Toyota, Hyundai, and Volkswagen, has taken legal action against the regulation. The group claims that the requirement for vehicles to automatically stop and avoid colliding with vehicles in front of them at speeds of up to 62 miles per hour (100 km/h) is “practically impossible” given the technology available today. The lawsuit was filed with the U.S. Court of Appeals for the District of Columbia, which will now review the regulation.

In its statement, the Alliance emphasized that while AEB technology has made significant strides, it is not yet feasible to meet the specific performance targets set out by NHTSA. Automakers also argued that the rule is overly ambitious and would place unnecessary strain on manufacturers to rapidly scale up technology that is still evolving.

NHTSA’s Position: A Step Toward Saving Lives

The U.S. government, on the other hand, strongly defends the rule, which aims to reduce the number of traffic-related deaths and injuries. NHTSA has stated that the rule could save at least 360 lives annually and prevent up to 24,000 injuries. This regulation is part of a broader push to improve road safety, particularly as traffic deaths have increased in recent years, notably following the COVID-19 pandemic.

John Bozzella, CEO of the Alliance for Automotive Innovation, sharply criticized the NHTSA decision, calling it “wrong on the merits” and “disastrous” for the industry. He argued that the regulation is based on flawed scientific assumptions and fails to take into account the challenges automakers face in developing and implementing the required technology in such a short timeframe.

The Road to This Controversial Rule

The drive for stronger AEB regulations comes from both Congress and NHTSA. In 2021, Congress directed NHTSA to set minimum performance standards for AEB systems as part of the infrastructure law. These systems use various sensors, including cameras and radar, to detect potential collisions and apply the brakes if the driver does not react in time.

In 2016, 20 automakers voluntarily committed to equipping nearly all new vehicles with AEB by 2022. By the end of 2023, the majority of these companies had met the goal, installing AEB systems in over 95% of their vehicles. However, critics argue that relying on voluntary compliance does not guarantee the effectiveness of the systems. Hence, NHTSA moved forward with the mandate.

Automakers’ Concerns and Legal Action

The Alliance for Automotive Innovation has long expressed concerns over the regulation, seeking to delay or adjust its requirements. In November 2024, John Bozzella wrote a letter to President-elect Donald Trump urging him to reconsider the rule.

While the original timeline for compliance was set to be three years, automakers have been granted an additional two years, allowing them five years to meet the regulation’s standards. However, industry representatives remain skeptical about whether this extended timeline will be enough to overcome the technical hurdles and meet the safety objectives outlined by NHTSA.

The Future of Automotive Safety

As the lawsuit unfolds, the debate over AEB technology and its role in improving road safety is expected to intensify. Proponents of the rule argue that AEB systems are an essential tool in preventing crashes and saving lives, while opponents within the auto industry caution that the rapid implementation of such technologies may not be feasible or safe under the current constraints.

The outcome of the legal battle could set a significant precedent for future automotive safety regulations, with implications for both the industry and consumers alike.
