Regarding station costs: can you include opportunity cost into your analyses? Maybe NYC is just far more economically productive than Paris, like if there are 50 story buildings all along that block, vs 5 story buildings in Paris...couldn't the cost even out because NYC is trying to diminish the disruption to local economy? Also hard to measure, but what are the QoL diffs between the two station methods, is one louder and more disruptive? I'm also wondering about technological differences. Can stations be constructed in a more modular fashion, can innovation occur to allow cheaper builds? And what about using more advanced tech in boring machines, like what TBC is trying in Vegas? Lastly, do we think a lot of stations is truly optimal? I don't know trains well, but if we get a fleet of SDCs in 20 years, maybe these can reduce station numbers by shuttling passengers their last mile or two, rather than building out billions of extra dollars of stations?
