Social Navigator.

That's how it's corrected and created all over the world.

That allows you to have the most correct map and the situation on the road.

I remember I went on the map of Yandex, which offered a short route. But I had to go back, because in that place you can drive only in the summer, and in the summer, there a section of the road is not cleaned and you can not pass.

At another place compared the travel time estimated on the maps of Google and Yandex, Google was very wrong, probably did not take into account the state of a large road section.

Waze has a living map from life today.
By the way, it was bought by Google for $1.1 billion.
