NEW YORK (CBSNewYork/AP) — Automatic emergency braking will become standard equipment in nearly all cars by 2022, federal safety officials and 20 major automakers announced Thursday.

The systems use cameras, radar and other sensors to see objects in the way and slow or stop a vehicle if the driver doesn’t react. They are already available as an option on many models.

The agreement calls for phasing in the equipment on nearly all models except some with older electronic capabilities or manual transmissions.

Mark Rosekind, head of the National Highway Traffic Safety Administration, said the voluntary agreement means that the important safety technology will be available more quickly than if the government had gone through the lengthy process of issuing mandatory rules.

Safety advocates have filed a petition asking the government to issue mandatory regulations saying voluntary agreements aren’t enforceable.
