That's not a giant surprise.  And it's not so much that opinions on TIGER
vary so much as the quality of TIGER itself is highly variable.  I've seen
places where TIGER was amazing and there wasn't much to do other than add
speed limits and turn lanes.  But Portland, Oregon comes to mind as an area
where it was pretty obvious that they digitized someone's hand-drawn map,
which was drawn on a napkin with a fine-tip ballpoint pen in the rain, and
was like trying to get a cat to cooperate with being rubbed backwards to

Given the inconsistency of TIGER data, I would not be surprised if no
automated effort will be ever attempted to deal with that dataset ever
again.  That said, there are tilesets out there that show TIGER data that
thas a newer name or geometry than what OSM has, though this itself has
it's pitfalls as I've noticed a tendency for such datasets to
false-positive on a name because OklaDOT renamed something and whatever
Census-taker mapped it in TIGER kept the old name.
