OK, lets sort this TC 'dangle berries' once and for all.
Firstly, its TC not ESP/ESC or manufacturers own gay names for Stability Control.
On 4 channel ABS units (98 onwards), it will very shortly after wheelspin apply the brake to the spinning wheel. If the driver just keeps the throttle buried, then it will tell the engine to reduce power.
On 3 channel ABS (pre 98), it will just tell engine to reduce power.
Now, just imagine for a moment that you wasn't showing off, or had no ability to drive, if you were driving a car without TC, at the first hint of wheelspin, you would feather the throttle to try to maintain traction. You should do exactly the same on a TC car - the electronics are there to stop you being a complete idiot, and driving like one will just keep cutting power until the car can maintain traction.
This is the same for any car with TC, and remember, many other cars use the same Bosch system. Similar applies to ESP cars, though that deals with all 4 wheels and can help lost grip in corners (although, once again, you would be a idiot to rely on it, as you are already beyond what the chassis can handle).
Additionally, as my car designer brother once told me (when discussing ESP on some Focus's), ESP is fitted to hide defficiencies in the chassis.
(Obviously, track/race/drift/show etc cars are a different kettle of fish, and hopefully driven by skilled drivers)
