Even with the traction control, physics is physics, if you're going too fast or changes direction too hard, you'll break traction and whilst the TCS will help you, if you don't know what or how the car will react you could still cause yourself some issues and to those around you. I've owned a few RWD cars but this is the first with traction control, and whilst it's good, you can still get caught out if you're not careful - fortunately I have access to quiet private road area where you can be a little silly (within reason).
Personally I don't think that a little bit of naughtiness on public roads is bad if it's quiet and there is no one around, but doing so with the knowledge that any damage you cause you will be responsible for.
