I have Adaptive Cruise Control on my FX45 and all I can say is DON'T GET IT... It sounds really nice but... when you on a HWY and go round a curve ACC thinks its a car and slams the protection on... if the car in the next lane is close to your lane and you go round a mild curve ACC slams the protection on... The only time ACC is good is when you on a very STRAIGHT and EMPTY interstate...

this is an option I would never never get again. It is the most uncomfortable safety feature ever I have ever felt and I found if anything it is not a safety feature but a hazard because when it engages round a curve it is so aggressive in slowing you down that it is dangerous.

If you prone to falling asleep at the wheel, think about it but for all other just pass on this option...

Maybe the BMW system is better but I can't imagine it is, your eye can tell when a corner is not a car, a computer can't.
