1010 – Using GPS When Driving
Justin: Okay, we’re ready. Let’s get on the road.
Fay: Wait! We don’t know where we’re going. We’re strangers in a strange land. Where’s our guide?
Justin: We don’t need a guide. See this? It’s GPS and it’ll help us navigate to where we want to go.
Fay: I’m not sure it’s reliable. We’re in a pretty remote location.
Justin: Relax and let me explain how this works: GPS systems use satellites to locate your current location. Information is transmitted to this receiver, so it always knows exactly where we are. We input the address of our destination and presto! It gives us onscreen or voice directions.
Fay: I know how a GPS system works. I’m worried that there aren’t reliable maps to where we want to go. I read that many printed maps of this region are outdated and unreliable.
Justin: Don’t worry. This GPS is the state-of-the-art. I’m sure it’ll be accurate.
Fay: A fool with a tool is still a fool.
Justin: What did you say?
Fay: Nothing.
