I have a 2013 Platinum XTS. I really like the car overall. But the one option that I wanted but wasn't in the car is "Driver Assist" to slow the car down when the cruise control is activated and the car in front of you slows down. I have "Driver Awareness" already which is ok.

So I was wondering if any Cadillac mechanic out there (or anyone else) knew if it could be practically added? This would only make sense our course if the car was basically "Driver Assist Ready" and you only needed to add the extra grill sensor/camera and connect it to electronics that were already there. I realize this is probably a long shot but you never know. (For the sake of this discussion, I'm not worried about violating any warranties.)
