I took a 90 degree left turn in the wet pretty fast the other day and I felt the DSC kicking in (toward the end) more than any actuating of adaptive drive. It was remarkable... the body roll during the maneuver was near non-existant. It caught me by surprise that the DSC had to intervene because it just felt like I was in control the whole time rather than sliding to the right in the cabin. It being a wet floor probably factored in, but the body roll control... amazing.

This is different than a slower more gradual turn like a slow-speed on-ramp that is banked... you still don't feel AD "kick-in" at any single point but you do feel some body roll opposite the bank as you start the turn. Sometimes I wish it were even stiffer because we take those types of on-ramps so much.

Basically what I'm saying is when you really need it, it will just work. But you won't always feel it - I guess it uses various degrees of damping.
