I've gotten perpendicular but only when trying. I've used full throttle when going straight the DSC does a marvelous job of keeping things under control.

That said with DSC disabled the car is unsafe on icy roads. When one side of the car has better traction the car steers itself like a bobcat and it can be a very quick very dramatic change in direction.
