My almost off topic contribution is this: One challenge I find in Latin America is that beyond the language barrier, there is a cultural issue with directions.

IME Americans tend to be the best at giving directions. They tell you "go 5 miles north, then turn right at the church, if you get to the bridge, you went too far.". Most are however skeptical you can ride 5 miles on a bicycle and have very little sense of terrain.

Latins tend to start "do you know where the blue church is?" They also tend to mention a lot of landmarks you will pass on they way, none of which require any action. Then when i pass the big mango tree, i remember something was said about a tree, was I supposed to turn here?

Many addresses in Costa Rica include nearby landmarks. "Next to the green church" or "diagonal from Pulperia Chepe". Some actually use the word "antiguo" which means it is no longer there. "Next to the former School".
