Open thread: what are NYC’s biggest transit mistakes and missed opportunities?

We all know there's room for improvement

For Curbed's first Transportation Week, we've regaled you with stories about the future of transit in NYC, the visual history of subway cars, what it's like to commute by bike, what it's like to navigate the subway in a wheelchair, the uncertain future of the city's horse stables, and so much more. And now, we want to hear from you.

In some ways, the history of New York is the history of its transit infrastructure: the 1883 opening of the Brooklyn Bridge underscored Brooklyn becoming part of New York City; construction of the Cross-Bronx Expressway destroyed underprivileged neighborhoods and displaced their occupants in the 1950s; and still today areas that lack robust transit infrastructure are among the poorest in the city.

And so, we want to know: what are some of the biggest mistakes, or wasted opportunities, the city has made or passed up when it comes to perfecting New York City's multitude of transportation options? (The demolition of the original Penn Station is the easy answer—we challenge you to dig a little bit deeper.)
