There's a limit of 5000 nodes on the static renderer to stop the server 
from falling over.  Until we have a way to distinguish "main roads" from 
others, or to cache the images, it's likely that looking at a whole 
continent will be less than satisfactory.

Of course, there are fun things you can do with millions of gps points 
for working out which roads are most important.  They might not agree 
with mapping agencies' ideas of important, but just because we can't use 
their data, all is not lost :)

There are also plenty of ways to simplify point and line data, so the 
5000 node limit is likely to be just a temporary hack.

Best,

Tom.
