The Blue Cruise is "interesting". I have used it a few times and it works well if you are on a major highway with consistent white lines on both side of the lane. Does not work particularly well on the right lane as the right white line is interrupted at entrance and exit ramps and you get a message to put your hands on the wheel. And it will also tell you to keep you eyes on the road if you look away very long. The adaptive cruise control works very well with it. I can see using it on a long drive across open country to relax a bit periodically.
