Just finished our first road trip in the 2014. Chicago to St Louis and back. Biggest surprise is I love the adaptive cruise control. I thought it would be an annoyance, keeping me from getting too close to the car in front. Instead, it was more like an intro to autonomous driving - the car literally drove itself in terms of speed. Too close, slows you down and maintains, car moves over to right lane, brings you back up to preprogrammed speed. No more hit brakes, slow down, hit resume when clear - a must have for highway driving now that I've experienced it. Probably old news on this forum but new to me.
I need to work on seat positioning as I did get a little lower back fatigue at the 4 hour mark or so. Got 21.6 mpg, mostly 75 - 80 cruising down 55.
