The whole thread is a little confusing...I was going off this comment in the last post in the thread:
"Even in the PP cars, like most other cars cannot completely turn those systems off. It is extremely numb, but not off. There are VERY few cars (mostly super and hyper cars, Viper, Lamborghini, Ferrari, AMG, etc...) that have this complete control over these systems as they are actual sports cars. "
