When i tried doing the same donuts with the vdc on, the system would not let me slip at all. I was just driving slowly in a circle with my gas pedal down to the metal. I'm thinking if the car was to interfere even with the vdc off, my scenario would have definitely triggered the interference. My front wheels were pretty much stationary and rears spinning very fast at different speeds. In case you're wondering if I didn't notice the intrusion due to it being 10% or 15% or some small percentage of a normal interference, I can tell you that it did not interfere. If it did, it failed miserably by hypothetically letting me crash into a tree while my car was spinning for many minutes.
