The problem is that doing so removes the ability to do the self parking, or doing something like the remote kill switch that they can invoke in case the vehicle is ever stolen. Me personally, I know how to park and particularly care if my car is stolen..that's my insurance companies problem. So I could live without both of these features, but you can see how some would argue the opposite. I'm sure there are other tie ins, I'm just can't think of any other that as obvious.
