Automatic emergency braking coming to all cars by 2022

The 20 automakers include 99% of the new-car market, says the National Highway Traffic Safety Administration, which is part of the Transportation Department. The agency, along with the insurance industry's safety arm, the Insurance Institute for Highway Safety, negotiated the deal. IIHS says it expects the deal will shave three years off the time it would have taken for a new rule to be implimented without the deal.

During those three years, IIHS estimates believes the deal will prevent 28,000 crashes and 12,000 injuries.

Automakers joining in the deal include Audi, BMW, Fiat Chrysler, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Porsche, Subaru, Tesla, Toyota, Volkswagen and Volvo. It will also be standard on most medim-duty trucks by Sepember, 2025.

“Deploying AEB on a wide scale will allow us to further evaluate the technology’s effectiveness and its impact on insurance losses, so that more insurers can explore offering discounts or lower premiums to consumers who choose AEB-equipped vehicles,” says IIHS Board Chairman Jack Salzwedel, who is also CEO of American Family Insurance.
