The only thing I've ever found Cruise Control useful for is avoiding a traffic ticket. If I see a police officer patrolling it's a tool I can use to go at slightly under the posted speed and only worry about traffic around me. When using the cruise control I find I actually have to pay /more/ attention to the vehicle actively, as I need to be aware of when to cut off an external (otherwise) uncontrolled system. If I'm controlling acceleration it's handled by more unconscious portions of my mind. I'm also a much more alert driver and far more aware of my present state of tiredness when I have to maintain interaction with the vehicle directly, including minute adjustments in speed with the accelerator.
