Where did Cindy get her information about "smart" cars?

M: I’m sorry I’m late, Cindy.
W: That’s all right, Joe. My house isn’t that easy to find. But you know, you wouldn’t have gotten lost if you had a "smart" car.
M: A smart car? What’s that.
W: I just read a magazine article aleut some new technology that can make a car smart. One device is a computerized map display and a synthesized voice, you must enter the address where you want to go, and the voice tells you how to get there, street by street.
M: Hey, that’s just like my brother. He never gets lost, and he’s always telling me the best route. So what else will smart cars be able to do?
W: Well, the article said that they’ ll be equipped with radar warning systems that will warn drivers if they’re getting too close to other cars with an alarm signal i and they’ll even put on the brakes if the drivers don’t.
M: Tell mc, Cindy, will these ears be smart enough to fill themselves up with gas?
W: Not that I know of. Why do you ask?
M: Well, I’m not late because I got lost--I’m late because I ran out of gas on the way over here.
