I am a soon to be owner of an S P90DL I've experienced autopilot during a test drive and really like having sensors lookout for hazards. It's like having another set of eyes watch the road. Before my autopilot experience, I was introduced to drive assist features by our 2015 Jeep Grand Cherokee Diesel. It has adaptive cruise control, blind spot monitoring, and cross path detection. Cross path detection alerts you when in reverse and a vehicle is crossing behind. This is most useful when backing out of a parking space with cars adjacent, blocking your view. During my test drive, I was told the S doesn't have this feature. I'm left wondering if the necessary hardware is present so that the feature could be added with a software upgrade. Any ideas?
