"Electronic Stability Control (ESC), which selectively applies brakes to one or more wheels when a vehicle is about to slide out of control, is **The Most Important** safety advance since the safety belt.
"Recent studies have found that ESC could save as many as 10,000 lives a year if all cars had the system. Begining in 2012, the federal government will require that all new cars come equipped with ESC."
People are working on Next Generation stability control, too. And this really sounds neat:
"New ESC systems will go further in managing vehicle dynamics. One system, ESC II, is designed to provide slight steering input, together with selective braking and throttle reduction, to maintain control. Rear-wheel steering control through an active multilink suspension is also being looked at to work with next-generation ESC, providing optimum stability."
