There was a (poorly) done import of house numbers done in San Diego county a long while back. Data from that import usually has a source tag of "SanGIS Addresses Public Domain (http://www.sangis.org/)”. I think a reasonable check for some of the questionable street names in that area could be done by verifying that at least some of the addr:steet tags along the way match with the name tag.
Unfortunately, I attempted a clean up of that import[1] a while ago so my edits may have muddied the water. On the other hand, in areas where there were objects with address information I did review the street name and addr:street against the most recent TIGER imagery available in JOSM at the time. So there is a good chance that I reviewed many of the street names against TIGER data. When you reviewed Orange County, how did you do it so quickly? The only way I know to go through this is looking at each one, one at a time.
