OpenStreetMap
Something strange has happened in the north of manchester/south pennines area. Most roads seem to have been mapped (probably from the imagery) but the ways are not marked as highways so they do not render. I'm not sure why this is but it's in need of much fixing!
I'm not sure if it's possible to check if the ways used to be correctly tagged and have lost them, or if they were never fully tagged. Tagging as highways will sort the rendering, but someone will need to visit to get all the street names.

I looked at one sample untagged way and it has no history showing that it once had tags so I guess this is just bad tracing where no tagging was done.

Some people think this is the right way to do it (see osm.wiki/index.php/Yahoo): Setting a highway tag without surveying supposedly creates a false impression of completeness.
