It's easy enough to build, but in the US that data is very, very far
from complete.

Even in Europe, you will find a lot of ways that are not tagged with
maxspeed. You will have to have a fallback mechanism with implied max
speeds for each road class, for each country you want to cover. And
that's going to be unreliable. You will have to decide if that's

Looking at services like http://www.itoworld.com/map/35#fullscreen, it's clear that much of the data is there. What's the best way to go about this? Anyone try it before?
