I see the point that you're trying to make. I haven't exactly driven a car with Active Yaw Control, but I have driven a Honda Prelude Type SH with ATTS. From what I understand it's essentially the same technology except the Prelude is front wheel drive instead of all wheel drive.
The loss of the AYC and ACD in the American Lancer is not the only reason why I'm disappointed. I think they made quite a few bad changes in the American version. Some of the reasons also make sense such as the weaker engine due to our fuel of lesser octane, the ugly front end which they claim was so that it would pass crash tests. But the Altezza styled lights and the different writing on the rear end was completely unnecessary. We lose the ability to change the traction settings for different surfaces. It's as if Mitsubishi totally forgot that we have Snow and Gravel here in the states. I'm doing 360s in my prelude over here in the snow, i was really hoping the Lancer would totally solve my problem.
It's sort of like when you rent a foreign film that's dubbed into English and you can't enjoy it because through the translation, half the plot was lost.
Mitsubishi has had a pretty dull reputation since they axed the 3000gt series and totally screwed up the Eclipses. I thought they were going to have something really special with the Lancer, IF and only IF they brought something a little closer to what they have in Japan. They saw how badly we wanted it. We let SEVEN generations of the Lancer pass us by. They promised they would bring us the Evo but they never told us it would be the Evo 7's retarded cousin; Evo BillyBob.
