The Focus had the option in 2001, I know I have it. And trust me when I say it can do a better job of keeping you on the road than a experienced driver, it can think and respond faster than any human. Some may say its a nanny feature but it is disabled via the botton down by the e-brake. I would say for the most part though it has a high threshold before it does its magic, virtually any "normal" daily driver would not even require its help unless in a panic/emergency manuvuer, and thats where it really shines. Anyrate for those of you how say its unneeded, I say you should try it before you knock it.
