>Perhaps because you don't state any mechanism on how the borders of a country increase the complexity of building a particular transit system This is HN. I shouldn't have to exhaustively spell out every detail like I'm on Reddit. I think that stating that a mass transit system that covers more people and more area leading to more stakeholders with more opinions who need to be pleased is more than enough. Presumably most people here have jobs where they work with other people and should be familiar with how increasing the number of stakeholders and/or coverage of a project increases technical and political complexity. Look at the history of public transit in the DC/Maryland/Virginia area for an example of political complexity scaling with the number of people and different jurisdictions covered. >China The land of "the subway is going here, don't like it then screw you". >Russia Which built out most of it's infrastructure back when it could operate similarly to China does today. I would think it would go without saying that having a government that unilaterally steamrolls any opposition to its public works projects is not a practical solution for mass transit in the west. >Canada In basically all of Canada you "need" a car. Most here would say that means they don't have good mass transit.
