Given that some parts of the world (such as North America) have as many states and motorways that allow bicycles as don't, I'm not sure any assumption is considered valid for bicycle accessibility for motorways and encourage people mapping North American motorways to research the issue and find out for sure if it's actually legal to do so. Fewer than 25 states (the ones that do are all eastern states with high population densities and typically motorways that have been grandfathered into the Interstate system but wouldn't qualify by modern standards) and no provinces prohibit bicycles (or pedestrians, for that matter) altogether on all motorways, these should have bicycle= tags explicitly set, and only by people who have researched the issue for the locale in question. >> ADDITIONALLY, there is a "local cycleway network" route numbering system >> being simultaneously proposed.

The latter seems like a misuse > of OSM. While I agree that OSM is to be used to describe what currently exists, it should be noted that in central western California, numbered bicycle routes are common and many more are often frequently proposed. I would hazard to guess that proposed routes are *under*mapped, not overmapped. >> When a route is "approved" by the local jurisdiction (city, town, >> county) just remove the "state=proposed" tag and the "dashing" goes to >> solid.

I disagree. If it's proposed (like LCN 50S, which is so early there's not a single route nailed down yet), it's proposed. Once approved, it exists, even if old or non-existent signage is still on the ground, as signage is often inconsistent years after the fact. If mapping routes on the ground was the exclusive goal, than most bicycle routes wouldn't exist in North America (based on the frequency the smaller signage is stolen), and Oklahoma would have at least 9 different parallel routes for OK 66 and three for OK 117. States don't have an infinite signage budget, so signage can take months, or more likely, years to decades, to update to reflect the reality of the situation. I'm still finding US 66 signs on residential streets that haven't been part of *any* highway (or even had lane delineators) in decades...that doesn't mean US 66 still exists.
