Yesterday I took ~1 mln rides we made in December and matched them to
the OSM road network. With that I found a few hundred points where an
actual trace diverged from the matched one quite often. This usually
means a oneway tag is wrong, or a turn restriction is incomplete.
The result is this MapRoulette challenge:

Thanks, Ilya -- this *is* fun! You've caught a lot of bad tagging
that's been sitting for years. Looks like we're about a third of the
way through these already. Teamwork!
I suspect that some of the problems aren't previous bad editing or even
TIGER issues, but actual wilful vandalism. I mentioned the problems due
to this user last year (see
https://lists.openstreetmap.org/pipermail/talk-us/2018-December/019144.html
), but as they keep doing the same thing and resisting all calls for
them to get in contact, I suspect it's probably deliberate.
I've just had a go at patching up their latest efforts (in changeset
67172109 and the one before it - I'll comment on that when the OSM
website comes back). The admin relations 175711, 175698 and 175708 now
look sane, but 397330 and 400000 look to have been broken for some time
and could definitely benefit from someone local trying to figure out
what is correct there (I'm guessing most of the wood one isn't).
Best Regards,
Andy
