Adaptive cruise control is fantastic! When I'm in "no hurry" or "really don't want more points on my license" mode I usually set cruise control, but in the UK few people use it. Therefore the speed of other cars tends to drift slightly, and you find yourself adjusting all the time. Adaptive control completely solves this problem.

I don't see any problem with being rear ended - the control is doing exactly what I would have to do manually. It is very smooth.
