That BMW sounds complicated. It has so many other features involved in it. First you have 400 hp, then you push a button and you have 500 hp. What about just driving it yourself? 500 hp, if you're scared, don't get behind the wheel. I have all the traction control I need, in my right foot. Its really common sense. People have come to rely on things such as traction control, abs, roll-control, etc.... Its scary that if these systems ever failed, the drivers would be endangering our lives by the way they drive.
I would still love to have that BMW, but imagine what it would cost if something failed on it? That'd be a car I'd lease for a few years, then take it back and get the newest fastest one.
