There's a station central-eastern Brooklyn called "Broadway Junction" that has as many connections as the largest transfer station in DC.
But they are still much less densely covered than Manhattan: https://cwhong.carto.com/viz/6dfca01c-47e5-11e6-9fd3-0ee66e2...
Mainly because NYC is the only US city with an extensive subway system.
Take a taxi from Harlem to the Botanical Gardens when there's no traffic (so never, or at 3-4am), you'll be surprised how fast you get there.
It's crazy how much longer the same distance feels when you can't just drive straight there with little to medium traffic!
It took her and most others around 12 hours; I can easily believe 20 if you're stopping at bars along the way :P
Isn't this because of road congestion though? I thought the principle behind the study was to remove all cars except those 3,000 ride sharing vehicles.
