Firstly, AFAIK, there is no debate that motorway should imply bicycle=no
What do you do when the DB says "Main Street" and the sign say "North Road"
? Perhaps it's a long street that changes name at some point. Perhaps you
find out that "Main Street" was added by someone with a history of being
inaccurate. Use your discretion. If you know that a certain sign means
"Schnellstraße" and traffic laws prohibit cycling on them by default, then
tag it with bicycle=no
The point is that it's much easier for OSM member number 989431* to tag
bicycle={yes/no} than it is for him/her to choose between 'primary' and
'trunk'.
* Yes, some people are contemplating having this many members !
