Meeting the Interstate highway system standards also qualify it as a
motorway, for the US. The sign is, for the most part, an indicator that
it meets these standards. Where it doesn't meet standards but is still
designated, OSM can make an exception just as the US gov't does.

One problem is that the signs have little to do with the real road
types. One potential solution to this is my proposal here:
It separates the signs from the real road types.
Unfortunately, reality is complicated and so are the definitions there.
