It would seem there is some variation on sensitivity, as said previously I have never noticed mine working on normal driving it's only after I got more aggressive with the pedal once stood that it worked. Indeed the whole esp asr on my car seems barely noticeable must see if I can induce wheelspin or not
Well been in the lakes and it did work but not consistently and I wouldn't like to rely upon it so it gets my vote as another pointless add on for modern cars along with auto wipers and headlights
