Given the question: Given the question "What is the purpose of the artificial voice on "smart" cars?" and the answer "To guide the drivers.", write a conversation that might have happened.
The answer is:
M: I'm sorry. I'm late.W: That's all right. John. My house is not 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 about some new technology that can make a car smart. One device is a computerized map display and an artificial voice. You just enter the address for where you want to go and the voice will tell 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 the smart cars be able to do?W: Well, the article says there'll be a device with read-on warning systems that will warn drivers with a long signal if they're getting too close to other cars. And they will even put on brakes if the drivers don't.M: Tell me, Shelly. Will these cars be smart enough to fill themselves up with gas?W: Not by now. Why do you ask?M: I'm not late because I got lost. I'm late because I ran out of gas on the way over there.
