Completely incurious? NYC has a lot of subway miles. This particular subway was repeatedly proposed and rejected as being too costly. And when it was finally built it turned out to be hugely expensive just as predicted. And now this unusually expensive line is being used as an example of all subway construction. That is kind of like trying to explain the cost of food by reviewing the menu at a top rated restaurant or calculating the cost of driving by focusing on luxury sport vehicles. Anyone who actually cares about calculating and comprehending costs needs to be careful with outliers. And what is with this "people like you" remark? If I had input into the NYC subway system then I would focus on deferred maintenance instead of building a fabulously expensive new line that will never produce a return on the money spent on it. The verifiable fact is that the Second Avenue subway line was known to be hugely expensive from the start. Cut and cover construction was not an option in this case. I make a point about there being a hundred years of detailed analysis describing why the Second Avenue subway could not be constructed for a reasonable cost and that makes me completely incurious? Have you ever bothered to investigate the previous proposals which were rejected? Not even realizing that you are committing to a "It's different this time" strategy creates problems.
