While any experienced driver could drive the M3 safely with the DSC off given enough wheel time, the problem arises when a less experienced driver decides to give it a go and randomly switches off the DSC to have some fun.
Correct, but now that stability systems are available, it is prudent to leave it on for normal/regular driving, regardless of skill, as no matter how well one drives within his and the car's abilities, the public road is an uncontrolled environment and things can happen where all the skill, awareness and preparation, may not be enough to help.
