I took delivery last summer and I also did not have the option for ACC, which was fine. My wife's car has it and I cuss every time I set the cruise and forget to turn the laser off.
The only time I've used ACC and enjoyed it was in stop and go traffic and I wanted to look left at the slums in Mexico as I was driving through El Paso. It allowed me not to pay attention to the traffic in front of me, which was horrible on my part.
