It's still about driver skill. If left unchecked, the engineers could build a car that would be impossible for a human to drive. Too fast, corner too hard, brake like it was on a tether, etc. So then it would be a case of building a car that just barely didn't kill the most capable human. That was F1 in the 60s, when you saw all sorts of weird stuff.
