I swear that I have "felt" VDIM intervening when I intentionally try to accelerate around a corner when it is icy in my work parking lot, and I never heard a peep from the car, but the light on the dash was flashing.

When the car feels like it should plow forward in a straight line and not follow the intended curve, I can feel something happening (I assumed that it was selective application of the brakes). The car then tracks true around the corner.

I tried the same thing in my wife's car (05 Accord coupe) and almost hit a parked car when it plowed straight ahead instead of turning. I can't attribute this to better tires, since I think the stock tires on the TCH (Michelins) aren't anything to write home about. They hydroplane and pull in small amounts of standing water/slush.
