My wife's Benz has adaptive cruise coupled with other safety features and these features together are the bees knees. These features actually saved her once when she was towing our boat and a van had a blow out just in front and to the right of her. Her ML 400's brakes came on slowed her down and pushed her to the side and she avoided a collision by inches before she even realized the car in front was crossing right into her. It is also awesome in a traffic jam or severe congestion. Adaptive cruise is one feature I would for sure like on my next truck if they could get it right when towing heavy.
