Indeed. The freedom to steer can therefore be seen as a dual-edged knife. It could help avoid an obstacle (or being hit from behind) but it can also send you off of the road.

"Strickly" as far as the physics of tyre behavior is concerned. From a driver's point of view, entering a bend at a speed of some 30% excess of the critical speed usually means going off of the road, with or without ESP.

If the car is oversteering (as it is after the second weight transfer in the video) it can help, but I have found that in extreme situations (like this) turning the steering on it's own isn't quick enough. The driver need to help it get some momentum.
