I once had a ride with a Porsche factory driver in a then-new turbo Carrera equipped with a new ESC system intended to compensate for excessive oversteer. He was muttering and swearing as he alternated between stomping on the brake and accelerator in a high-speed corner, attempting to get the rear end loose. Just didn't seem right without unpredictable oversteer. Might add that Nader's "Unsafe at any speed" spent a lot of time panning the Beetle.
