pride355:
1) If you ever have to lift off the throttle in a corner, the car immediately starts to oversteer and this kind of oversteer, unlike throttle oversteer, is very dangerous. I always drive my cars DSC/PSM off unless it is raining. Once. I was fast into a corner and just in the middle of it, there was a car on my lane and I had to slow down so I lift off the throttle. Once I released the throttle, I had a sudden oversteer, I over corrected it and it went to other side. I countersteered to other side again. When I was just thinking that I'm loosing the back end completely, my lane had cleared and I just put my foot on the throttle and catched the back end. As soon as I regained the control, I checked the speedo and it was 155 km/h. It was the scariest moment I had in my 997. After 2 weeks from this incident, I wanted to try the same corner again. I was little aggrasive and quick with the steering wheel and never lift of the throttle. In the end my exit speed was above 170 km/h. So, 2 different scenario with huge speed difference.
Well described, but this is the reason that I would tend to use PSM on the road (and turn it off on the track, if desired). If you feel PSM is too intrusive on the road, then engaging Sport (with Sport Chrono option) will raise its threshold. If you find this is still too intrusive for the road, then you might be driving a bit faster than is safe (not to judge - it's your choice).
