There are different types of adaptive headlights. My Cadillac has headlights that check for cars in the headlight's path and automatically dim or switch on high beams. Curve adaptive headlights either have motor driven headlights that track the curve of the road, or LEDs or light channels that can be activated to specifically illuminate road areas, but not blind oncoming drivers. It's definitely cool technology, but I'm not sure how vital it is, or how expensive it is to repair/replace.
