They built a whole new subway stop right in the middle of it, and it’s walking distance from Penn Station. It’s a wonderful model for transit-oriented development.
If you choose to drive a private car in Manhattan, that’s on you. As a Manhattanite myself, I assure you that most of us don’t own cars. It’s just not how we get around. There will be increased delivery and taxi traffic around these new buildings, but 99% of the people living and working at Hudson Yards will arrive by means other than a private car.
