And, (2.) to cause cars to be slower in an often small and confined area.
Road courses are designed for maximum safety at maximum speed. I'm just pointing out the differences, this is why I could see how someone could push a car street car too hard at a suspension-demanding auto-x course, lose control, and flip.
No, you're not understanding what I'm saying. The "fluidness" of a road course has nothing to do with this. It has to do with inertia and physics. At 100 mph, the tires won't get quick impulsive forces strong enough to flip a car. They'll just slip over them. It's the slow speed, and not this concept of "acrobatic maneuvers" you keep bringing up that's the cause of flips in autocross. In every case I've ever heard of, the car slid (happens the same in both road courses and autocross), and the tires caught.
It's only a few poorly designed suspension'd cars that have tendencies to flip otherwise....such as the E30 BMW and the Focus.

The typical car you see on a road course does not have stock wheel rates or shocks. The suspension loads and unloads very quickly and is highly controlled by high rate absorbers. There is less suspension movement. There is less body roll which leads to less weight transfer. And less weight transfer means the car is less likely to roll over.
This is entirely about stock suspension cars being overdriven to the brink and then driven past the brink by a 'superhero'.
Total amount of weight transfer cannot be changed via less body roll. It can only change via CG height, track width, and amount of grip.
