I like how DSC intervenes when necessary, but never prematurely or too intrusively. In some cars, a warning buzzer will even sound (*coughToyota*cough*) and the system will take away all power away from you, even when it's just minor slip. But in BMWs, it's just right.

I was driving to the rear exit of a BMW service centre today, and water running down the slight hill had frozen over part of the roadway. As I went around the bend, I purposely put a bit of throttle to kick the tail out a bit, and the DSC brought it back together smoothly and perfectly. Makes the driver look good!
