I think the issue is advocating driving your car to its physical limits on public roads, as opposed to just appreciating the extra margin of safety having more cornering ability allows in case of an emergency. Or to make a good analogy, what you do is more like carrying a gun for protection. You have it, it makes you feel safer, but you won't feel a need to use it unless your life depends upon it. His version is more like I have this cool gun and want to shoot at targets while standing on a busy NYC sidewalk. Sure, I'm a great shot who will never miss (except of course when you do, and someone accidentally dies as a result). Cars should only be intentionally driven to their limits on a track (maybe I'll make an exception to that if you're on an empty road in a place like Nebraska).
