The days of fighting over who gets to choose the music during family trips may soon be over, thanks to a collaborative effort between DaimlerChrysler Corporation and the Massachusetts Institute of Technology's (MIT) Media Lab. The Dodge MAXXcab concept truck is the first automotive application of Audio Spotlight(TM) -- an MIT Media Lab technology that directs a narrow beam of sound much like a spotlight projects light. Only the person whom the sound beam is "shined" at can hear it. This makes it possible for each passenger to listen to something completely different without interfering with each other.
