Does it tale into account wheel spin? How does it cope with different surfaces like gravel or snow/ice, which have less grip, and therefore you would have to split the power earlier to avoid losing grip.
What I'm trying to say is: If it takes input from the sensors you mentioned above, and then pre-empts any wheel spin, how does it know what surface you are driving on? The surface would make a difference because you begin to slid or loose traction sooner on gravel, etc than on the road.
It certainly seems like a great system, all I can get from it is a couple of 'chirps' when taking off quickly while turning. I tried it around a sharp, low speed corner in the wet the other day, it just seems to pull into line when you plant your foot. It's quite hard to get used to compared to my previous 300ZX, which was always happy to go sideways in the wet even with 255's on the back.
