POWER TOURISM

Forgot the map? Left the guidebook at the hotel? No problem. The GoCar is a three-wheel tour guide equipped with a GPS system that not only tells you where to go but also describes the sights once you reach them.

Currently available only in San Francisco, it goes up to 35 m.p.h. and travels a 12- to 17-mile loop.
