I hope the DSC was off!
Ha ha!! You're havin' a larf!!
I've driven BMW's of all sorts over the last 10 years (used to be a BMW salesman, sorry!!), and for most of that time I drove everywhere with DSC off.
However, on this occasion, discretion was the better part of valour as I have a healthy disrespect for my own driving skills, and DSC stayed firmly on!! The track was soooo slippery, and I really, really didn't want to trash my work car that's on finance!!
In the end DSC saved my bacon a couple of times (as in "every time" for the exit at Druids ;-)), and for a big moment at Surtees when I clipped a kerb (the instructors had warned us not to, but there you go!!).
But I do agree, if you're a competent driver in good conditions, DSC can interfere quite significantly with you're driving enjoyment!!
