I think I'm just to old and old school enough to not trust any kind of hands free driving of any vehicle I'm in.
I used to think the same…
My wife’s Grand Cherokee does not have full hands free, but, if you put, literally a finger on the wheel for “pressure” it will keep you centered in the lane.
4 hour drive up north, about half of it I used this in conjunction with ACC, I gotta tell you… it changed my mind.
It did a really, really nice job of keeping it in the center, even at some rather sharp 75MPH sweeping curves on the expressway.
