A legal challenge accuses the National Highway Traffic Safety Administration of failing to meet its congressional obligation to establish fuel-economy standards at the highest achievable level. The lawsuit argues that current regulations do not reflect the "maximum feasible" efficiency required by law, potentially undermining efforts to reduce emissions and improve vehicle performance. Critics claim the agency has not fully utilized available technology or economic conditions to push for stricter standards. The case raises questions about whether regulatory decisions align with congressional intent on automotive efficiency.
