I've yet to experience this tbh well yet to experience it slide alot, had it step out once but i was expecting it to and it was much of a slip.
scariest moment for me was yesterday when i was foolishly following a porsche who was overtaking a car, i missed judged the roads and had esp/tc or what ever it is kick in as i changed gear causing the the back end to step a bit in the direction of the car i was over taking, soon slowed down after that.
