I know very specifically of someone first hand who took too much speed into a corner, tried to give it a bootful to induce oversteer (rightly or wrongly) and had the car brake the inside wheels and cut all power. Net result is he went straight on and hit the armco being totally unable to alter the direction of the car.
I don't really want to get into arguing about which of the varying stability systems caused this to hapen because I wouldn't understand them anyway frankly - it just did. I prefer facts to wikipedia
