Sources: Automatic Braking to Be Standard in Most New Cars by 2022

— -- More than 10 major auto manufactures and U.S. officials have agreed on a plan to make automatic emergency braking standard equipment on most cars by 2022, sources tell ABC News.

The U.S. Department of Transportation and the Insurance Institute for Highway Safety will make the announcement Thursday morning from McLean, Virginia, where they'll be joined by representatives from several global automakers, the National Safety Council, and Consumer Reports.

Research from the Insurance Institute for Highway Safety shows that systems with automatic braking reduce rear-end crashes by 40 percent on average. The same research says this technology could prevent some 700,000 crashes and 300,000 injuries every year if installed in all vehicles in the U.S.

The manufacturers making this commitment tomorrow represent the vast majority of current U.S. car sales.
