Even before you climb inside, the GoCar is clearly a car with a personality. The petite, three-wheeled two-seater has a hood that slightly resembles an eager-to-please smiley face, and an open top that seems custom-made for letting the breeze ruffle your hair. Then the real fun begins: built with the company's own software and a compassion for the voiceless robots of America, a talking GPS system guides two-seater GoCars through the city streets of San Francisco, San Diego, Miami, Barcelona, Madrid, and Lisbon with cheerful, info-rich narration. Second only to having a knowledgeable local jog alongside your minivan, tours zip along at drivers' own pace and accommodate as many pit stops as time allows.
