Computers in CarsYou're far from home on a lonely road. Shadowy forests stretch away on both sides. A thick mist (雾) makes it difficult to see far beyond your car's windshield (挡风玻璃).'Can this be route 90A?' you wonder. If it is, you should be near a town. Yet there's no hint of one. Night is closing in. And you're low on gasoline.This is a situation where an in-car computer that can navigate would be a big help.
