I turn it off every time I start up the car. I've had my Z since July, and you could count on one hand the number of times I've smoked the tires intentionally, so it's not like I drive around like an ***. I just don't enjoy the computer jumping in and assuming that I need help. To me, the way I learned to drive RWD sports cars, having it on is actually more dangerous. Robbing me of both power and control when I most need it.
Just remember to turn it back on when mom is taking your Z to the grocery store...
