my car has DSC, but i never use it..
The default condition is that the system is always engaged.
i was curious, does anyone drive with it on? should i?
I rarely disengage the system.
is it only ment to be used in poor driving conditions?
It depends upon your driving style. DSC gives you the ability to drive your car to the limits of adhesion without fear of losing control. When you push your car to an oversteering or understeering condition, DSC intervenes to help you correct the condition by applying the brake to a specific wheel and cutting the car's power if necessary. Of course DSC can't overcome the laws of Physics. So if you drive like an idiot, DSC won't help. On the other hand, DSC would only be engaged in bad weather if your Grandma drives your car.
