I lived on 2nd Ave for years in UES and biked to FiDi for work - cannot relate to what you're claiming here. Yes there's noise, it's NYC, but "gridlocked traffic and construction" was not something I'd normally run into.
Per car, per minute? Sure.
Per car, per trip? Not clear, but probably not. Per block, per day? Also not clear, but probably not.
Still, when living in NYC I felt constantly surrounded by car traffic, far more than other cities I've lived in.
And the construction, you can't deny the amount of construction going. A lot of it isn't even active work; contractors seemingly throw up scaffolding and let it sit forever because I guess the fines for letting scaffolding sit forever are cheaper than the costs of fixing crumbling masonry facades, so that is what is done. Don't get me started on the trash situation either, what an embarrassment that corrupt aspect of nyc life is.
