This has been an interesting discussion, from the perspective of several different viewpoints. I'm accustomed to dealing with the "go fast- - - -turn left" crowd, where we put a bunch of vehicles so close together they could pass notes to each other out the windows, for dozens of laps, and we do it at speeds well over 100 MPH. ANY unintended steering input under those circumstances is too much, and it can wreck the whole crowd. With that in mind, we go to extreme lengths to make sure the steering and suspension does exactly what it's told.
With a couple of traffic lanes to play around in, at speeds half or less what the round trackers deal with, I can see where herding an unpredictable vehicle in the general direction we want it to go might be acceptable. I just look at things from a different point of reference.
