speaking of adaptive cruise...I'm on the fence about that particular technology. It beats tapping the brakes when you approach a slower vehicle but it can get aggressive in braking as well and I've even had it brake when it picked up the scent of a car in the other lane. Do the brake lights come on when it brakes aggressively? If not, the person behind you has no idea you're slowing down quickly. I could see how someone could get in trouble in the right situation. And, you can get behind slower traffic and just tail them at 60 mph until you figure out you're only going 60 mph instead of 75. There should be some kind of aural and visual notification that it's on. I get busy working while I'm driving! I need notices. I'm on the fence on it. Leaning towards preferring to drive the car myself.
