(Trim the crap and return to sanity ;) )
The definition in the UK would mean that motorway and motorway_link ARE always 
one way and anything that needed to be two way would not be flagged as 
'motorway' but no doubt parallels in other countries are not quite so clear cut?
Perhaps the OSM definition of motorway should include the restriction of a 
single direction carriageway and move anything else to 'trunk'?
