What we absolutely don't need is someone making assumptions about 
somebody else's sources and adding random tags based on those - I don't 
see that chriscf's "fixme" edits add any value.  Personnally I do tag 
"maxspeed=national" on local A and B roads where there's a sign (and 
I've noticed it) because locally (Derbyshire) many/most A roads are 
actually maxspeed 50; adding maxspeed=national should mean "someone's 
been there and confirmed that that's what the sign says" not "someone 
who hasn't been there has guessed that it's probably a limit of XYZ".  
Maybe I need to start using something like "source:maxspeed=sign" as well?
