I can't stand lane assist that tries to keep you in the lane by actually moving or vibrating the steering wheel. To me, it feels like the car is slipping. That shit gets turned off right away. But I have driven some cars where the lane assist just beeps, and doesn't force the wheel at all, I can deal with that.
I find HUDs extremely distracting, they get turned off too.
Adaptive Cruise Control is extremely useful, I love that one.
No, silly, the problem is when it vibrates when you are nowhere near the lane dividers. I don't drive a BMW, I know what turn signals are for.
