answer:I’m not comfortable with the since of giving up control, especially when roads might be bad and more importantly I don’t trust the divers around me to be any sort of reasonably intelligent drivers. The only time i’ve used it is on I-5 from LA to Sacramento and I always had to deal with the occasional jerk who decides to swerve out into the opposite lane then back to mine just to take that extra 12 feet. True that i can always disable it at an instant, but i think CC lulls me into a false sense of alertness.
