From what I've read the speed sensitivity really isn't worth it. If you mimicked the vue setup then you would have an assist "curve" for a small SUV, not a classic mustang with whatever steering setup you have. It would take some fiddling to get it to feel right, if you even could. But with a knob, it sounds like most find the sweet spot quickly, then set and forget. I don't have a problem turning a knob for parking lots or freeways or whatever comes in between, I bet I barely ever adjust it once set.
