> Why does any transport discussion on HN become train focus?
Hypothesis: people aren't familiar with New York's trains. It's a world-class network the likes of which we don't otherwise have in North America. (Sorry Toronto.) So when they see eVTOLs, they emotionally map it to their local trainless context.
... I mean, no. It's more that it is weird that there is no train to the airport (it looks like you can take ~3 trains from Manhattan). New York is likely the only really big city in the developed world where this is the case.
In Ireland, everyone thinks it's pretty ridiculous that there's no train to Dublin Airport (all going well, it will finally have one in 2036 or so, after _many_ false starts). Dublin's a city of about 1.5 million people. It's pretty incomprehensible that a city ten times the size wouldn't have one.
I don't fit the hypothesis - the two cities I've lived in (Berlin, Seoul) have excellent trains. So it's perhaps overfitting in the other direction.
