Can you please enlighten us the "many situations" where it "MUST" be switched off. I can only think of one and it doesn't relate to driving on public roads. I don't know about Australia weather condition but here where I'm living we have three months snow and ice, on the icy surface, with Traction Control on the system don't allow the wheel to spin and the vehicle can't move at all and the driver should switch off the VSC and after pushing the pedal again switch it on then the vehicle start to move with helping Traction Control. time you should really turn traction control off is when you deliberately need to spin the wheels, for instance, to free yourself when stuck in snow or mud.
