It’s a fact that your car will stop in a shorter distance if we can keep the wheels rolling, sliding or skidding the tires will increase your stopping distance. These systems were designed to keep your wheels rolling in a panic stop. Each wheel has a sensor to let a computer know if the wheel is spinning, if a wheel stops in a hard stop situation the system will remove some of the pressure to that wheel and allow it to spin, in turn shorting your stopping distance.
