One more point to add to my original post.
A lot of this stuff is implemented rather badly, even unnecessarily.
The more of this stuff that's added (especially if it's very noticeably there), the less character a car has. Sure, better fuel consumption is great, but if you buy a new SLK, do you want that? Or do you want to feel like you are controlling the car, directly connected to the thottle butterfly?
I guess they know which will sell more cars..
If I buy an Alfa Romeo GTV, or a Lotus Elise, I sure as hell don't want to feel like the car is being a HINDRANCE rather than a HELP, which won't happen until we get seamless, un-noticeable integration.
P.S. Anyone ever drive a Citroen XM??
