There are definitely plenty of motorways around the world that allow bicycles. Where I am (Melbourne, Australia), they do by default - those that forbid them have signs saying so. IMHO, the approach "the wiki says that in country X, Y is the default, therefore I don't need to tag it" is excessively optimistic. Until there is an automated, easy mechanism for querying defaults (ie, a web service), it's much safer to tag explicitly. Also: yes, someone should make such a web service. Something like: get_default_for_way(way_id, key_name) => returns implicit tag value for the specified key_name, or "" if none can be deduced. get_default_for_way_by_tags(lat,lon, way_tags*, key_name) => returns implicit tag value for the specified key_name, if the way were subject to the jurisdiction at lat,lon, and had the given way_tags. For that matter, a whole range of interpretive services would be really useful and give renderers, editors and mappers some certainty.
