Golden Canyon is really really not a residential road. We didn't have the highway=road tag back when the original TIGER import was done, but I see many roads in the US tagged as residential that are anything from a freeway to a dirt track and most things inbetween. Perhaps, if any tiger data is re-imported a lot of the roads tagged as highway=residential should be replaced by highway=road, particularly outside large urban areas. This would at least make it easier to see what does or doesn't get touched afterwards. > > I had also noticed problems in San Francisco, where there were two Lombard > Streets on top of each other, one with the squiggly bit straight. > Fortunately someone has corrected this. > On a side note, I believe that the correct thing to do is to just delete > the "Tiger reviewed" tag rather than turn it to "yes". > Is this correct? > > I'm firmly convinced that automatic uploads should only go into areas where > there are NO user edited nodes or ways.
