The route is usually shown in great detail on your car's display. You also get a voice prompt just before you need to start thinking about turning. Is this a genuine problem?

I meant as a pedestrian.

Why would I speak this question when I can just look at the map phone for an extremely quick and concise answer?

Or if I'm driving, GPS is displayed on a giant screen.

You need to take out the phone and start the phone map app. And quite a few people are terrible at reading maps.

Not saying this is for everyone, but there will be users.

I assume this pin will use GPS? It’s not always accurate. Sometimes the GPS is off. With a phone screen, you can better estimate where you’re standing by looking around you and then comparing what’s on the map.

For example, the GPS is almost never accurate in Hong Kong, when I visited.

Apple Watch and Android Wear solve this.
