I’m one of those guys who thinks he has a natural radar. So it’s a little damaging to my ego to admit that I have a GPS app and use it often. I have to say the radar in my cranium has glitches sometimes. Since I started using the app, I haven’t gotten lost. The app gives the best route by avoiding traffic, and it will reroute me when I miss a turn. Admittedly, these are things my natural radar can’t do.
