17. A Computer Car p.105

You are in a strange city. It's late at night and you're tired. But you can't find your hotel. You sigh a
deep sigh. It seems like you are dreaming a terrible dream. What is happening?
This situation often happens to people who travel by car. But it may become a thing of the past. New auto
computers are being designed to tell you how to reach your destination. A small screen in your car displays
a map of the city and shows you where you are. Just give the computer the name of your hotel. You'll see it
on the map. To top it off, a voice will give you directions while you drive. With a car like this, what else
would you expect.
