The legal notice on the bottom of the map makes it clear that their data 
is not available for use in OSM. It has a personal-only, non-commercial 
use clause which is not acceptable.

In general OSM is not about using other people's data (though we do 
sometimes import data from other sources with their permission) it is 
about gathering the data for ourselves. That way we know it is correct 
and up-to-date and that we can use the data freely and without any legal
