> Street congestion is increasingly a problem, not so much because it slows down private cars but because it slows down buses. Those bus delays in turn increase subway ridership, and overcrowding slows trains loading and unloading.

I think the issue is population growth not matching funding (or Albany robbing us). I don't doubt that this contributes, but I'd be surprised to see people switching from buses to subway being a leading cause of subway congestion.

> Although uber does probably deserve some of the blame t

Again this seems like a really small thing. I doubt uber created many new taxis, so much as absorbed yellow/livery cabs. I'm sure it has an effect but I don't think it's the core issue.

> The answer is a congestion fee like Bloomberg wanted to put in.

100% agreed with the congestion fee, bummed it didn't happen.

> That leaves the majority of Manhattan with spare subway capacity to move people around.

I don't think this is true. One of the reasons the green line is so overcrowded is because so many people work on that line. It's not only about where people live. If you put people next to the E, it doesn't mean they only take the E.

> it is because of crowding on the Lexington line that I suggested densification should start at the south-west part of the neighborhood which has access to the sixth avenue line subways.

I agree that we should rezone and that the preservation stuff is a nightmare.
