Or if I took a rendered Mapnik map and then traced the streets. Any creativity within the original work would likely be gone. Or, for the areas I'm interested in (mostly in the United States) I'd just go back to the PD TIGER data and then trace only the parts that have been significantly modified. Overpass information is likely not copyrightable. So that part could be imported automatically. To be sure, if I wanted to free OSM from copyright, I'd make my own designations of roads as primary/secondary/tertiary/etc (and probably use different designations all together). I'd choose the categories of POIs to extract, and leave out the others. (I don't think individual POI latitude/longitude pairs are copyrightable, but the selection of which POIs to include and which POIs not to include might be.) Personally, I wouldn't bother with all this, because CC-BY-SA is fine for me. If OSM goes to ODbL I probably will use some of these techniques when extracting modifications made after the fork with my area of interest, though.
