Nope, motorways stay (at least if the default resolutions are used. By 
default no resolution 14 is created. But compiling Europe at 14 with 
motorways looks crap. Been there, done that. If you decide to add 
resolution 14 into the build, then yes motorways are not visible and 
only sea and big cities -- in reality we would want to have a seperate 
overview map for resolutions 14&16 that is only shown in 
Mapsource/Qlandkarte GT, as on all GPS for resolution 14 and 16 the 
basemap is the better match (a lot quicker to pan) for resolution 14 and 
16).

What I did really lower are motorway links to 18. They are not really 
visible (too small) in resolution 16 anyhow, and slow down the GPS. Also 
at such a resolution you never actually drive in your car, 16 is 
basically only for getting an overview on a country basis - hence 
motorway links are not needed). I did not change motorway junctions, 
that indeed might be handy at low resolutions (though basically at 
resolution 16 you don't need detailed junction layout, as in nearly all 
cases to motorways crossing there are junctions close to the crossing).
