Exactly. It is slight.
The other annoying thing to me is at least on my 2013 after the initial set, I can't adjust the speed by individual mph.. only to the nearest 5, ie 70, 75, 80. That's the primary reason I don't use the radar cruise, personally.
I usually cruise around 72 to save fuel on my trips to colorado... and am amused by the number of people that come flying up behind me on my trips across north texas.. only to slow down and follow when they have tons of room to pass.. too zoned out by their auto cruise to know they are doing 10 less than before. I've had this go on for considerable time before, at which point I'll start gradually slowing down to see the speed at which they notice. As long as it's safe. I've had people not realize they are doing close to 50.
I am an advocate for adding movable chicanes to random roads. We've dumbed down the average driver to the point of stupidity.
