I did a fair amount and noticed similar things — some of the suggestions concern private drives, others are not corroborated by available aerials. But I did find a decent ratio of fixable things, and as you go through the tasks, you get a better sense of which ones are likely to be fixable. The rest you can just mark as too hard or not an issue.
As for TIGER fixing, I was inspired by Mike N’s posting about his TIGER fix up effort and figured you can use MapRoulette to do some of it. A comprehensive review of TIGER roads is probably best done using his Tasking Manager approach, but to review just the ‘main’ roads MapRoulette is quite usable. I created a challenge for Utah as a proof of concept and working my way through the tasks: https://maproulette.org/mr3/browse/challenges/3610 <https://maproulette.org/mr3/browse/challenges/3610> If you want to help out, great. If you want to recreate this challenge for a different area, let me know. The overpass query can easily be adapted.
