Automatic Emergency Braking Systems Are About to Be Everywhere

Until a few years ago, automatic emergency braking (AEB; sometimes called autonomous emergency braking) was an exotic and rare auto feature, limited to high-end luxury models. But then came Subaru’s unveiling of its EyeSight AEB system on some affordable 2013 models.

Now, 20 automakers -— challenged by the federal government’s National Highway Traffic Safety Administration (NHTSA) and the trade group Insurance Institute for Highway Safety (IIHS) -— have promised to make AEB a standard feature on virtually all new cars by September 2022.

NHTSA predicts that most automakers’ acceptance of the challenge will make AEB standard on new cars three years faster than could be achieved through the formal regulatory process. And the feature could be arriving a lot sooner than 2022.
