Driving downtown, not THROUGH it. Driving THROUGH downtown means driving THROUGH downtown, not going towards downtown.
So Musk made a minor mistake, so the NYT reporter made few minor mistakes. I don't see lies, just two different sides of the same story.
Of course the NYT reporter could have driven downtown and take FDR uptown, but I don't see any prove of that. That would make a little sense if you took Holland, but not Lincoln tunnel.
minutia. my point was: its minutia.
You're other points are meaningful, though.
Anyway, to anyone outside of NYC, downtown is where the streets are crazy and one way and lots of business takes place... so, really, by that definition, anywhere below Central Park can be considered 'downtown'... especially if you are uptown.
