That is also why GPS units that learn are much better. I remember using a GPS app in my WM Device which even warned me if I was speeding. It would plot several routes and it allows you to review them. You can pick the route, and if you find that there is an error in that route, or an obstruction, such as road repairs, a closed private gate, or something, you can block it off the choices and it will never turn up again.

Okay sana if your GPS changes maps based on the time of day. There are areas na one way in one direction kapag morning, and one way the other direction in the afternoon.
