I just read about a new feature being introduced in some 2008 cars where the parent can hit one button ("time out" button?) and instantly mute all the A/V going on in the car and... get this... project their voice throughout the cabin!
As a parent, I have to tell you that this is an awesome feature. Its one of those that seems so obvious that you wonder what took them so long to come up with it, especially as it doesn't require any unique technology, just some innovative thought.
