Years ago I heard that Apple was going to use OSM data for their map app. I contacted OSM to remove our driveway. They did demote our driveway to a "private road" (the best I could do). Luckily, our driveway is not in the Apple maps app. I am still somewhat irritated particularly when I see our driveway in apps like this.
Hopefully you'll make a few more corrections as well, but even if this is the only edit you make, it is a contribution to the whole.
TIGER doesn't have all that much differentiation for minor roads, and the import didn't do anything other than a direct mapping of TIGER classes to specific sets of tags. For unnamed residential streets, it probably should have considered things like length and connectivity to downgrade a bunch of streets/roads.
