Cart-guided San Francisco tour

Tourists in San Francisco can ditch their city map and find their way without getting lost, if they rent a GoCar vehicle, a three-wheeled, two-seat car that looks like a motorcycle merged with a golf cart but with a global positioning system as their tour guide.

GoCar, manufactured by Trigger Technics of the Netherlands, guides the visitors via a GPS unit and a computer database of audio clips commenting 105 San Francisco sights and features. When the G.P.S. system senses that the cart is passing one of the points in the database, the stereo plays a story or gives directions.
