Car Safety Evolved: From Seat Belts to AI Brakes

Car safety features have undergone significant evolution, driven by engineering innovations and U.S. regulation. Early advancements, such as laminated windshields introduced in 1927 and the three-point seat belt patented in 1959, focused on occupant protection during crashes.

Later developments introduced features like crumple zones, head restraints, and airbags, designed to absorb impact energy and mitigate injuries. Systems such as anti-lock brakes and electronic stability control emerged to help drivers maintain control and prevent accidents altogether.

Mandatory regulations transformed many optional safety features into standard equipment. By model year 1998, driver and front-passenger airbags were required. Automatic emergency braking, a critical crash-prevention technology, is set to become mandatory on new light vehicles in the U.S. by September 2029.

These advancements collectively demonstrate a layered approach to safety, combining passive protection during a crash with active systems designed to avoid collisions. The ongoing development highlights a continuous effort to enhance vehicle safety for all road users.
