This could be the coolest iPod accessory yet: Chrysler's GEM division has introduced a docking station on wheels. And, it can carry you and three friends along with a tune. GEM calls the new docking station "Peapod," and it is actually a futuristic neighborhood electric vehicle, or NEV. Unlike the current GEM car that has an exposed tubular structure, the Peapod offers a sleek, ultramodern, and fully enclosed form. In contrast, when it rains the current open GEM design must be enclosed with accessory cab components if you want to stay dry.
