This is probably one of the better VSC systems out there. I know you don't get much snow there but around here in the winter it will not let you get out of shape in 2 or 4WD. It does well.
Can confirm. Even with VSC off, the anti-skid control on my old '08 would still prevent any and all shenanigans in the snow and wet rods.
