The National Transportation Safety Board (NTSB) in the United States has recommended that the “life-saving benefits of currently available collision avoidance systems (CAS)” become standard on all new passenger and commercial vehicles.“You don’t pay extra for your seatbelt,” said NTSB chairman Christopher A. Hart in a press release on Monday. “And you shouldn’t have to pay extra for technology that can help prevent a collision altogether.” NTSB released a special investigation report The Use of Forward Collision Avoidance Systems to Prevent and Mitigate Rear-End Crashes on Monday that stresses that CAS can prevent or lessen the severity of rear-end crashes, thus saving lives and reducing injuries.
