Electronic stability control

Overview
"Electronic stability control (ESC) was introduced in the mid-1990s and became mandatory in the United States in 2011 for newly manufactured light vehicles. When the driver presses the brake pedal, ESC combines data from multiple sources in the car to selectively apply the brakes on a subset of the wheels, leading to increased control on turns and slippery surfaces. The National Highway Traffic Safety Administration (NHTSA) estimates that ESC saved over 2200 lives among passenger vehicle occupants during the three-year period from 2008 to 2010."
