Sure. Could you point me to a source better than watching hours of video? What's the cost per length of tunnel? How many people can be carried per hour? What level of service interruption is allowed? How accessible is it for wheelchairs, strollers, and such? The sources I can find say things like "The system is designed to transport more than 4,400 convention attendees per hour across the campus." for https://www.lvcva.com/vegas-loop/ https://www.lvcva.com/vegas-loop/ and "The highest daily capacity of the system during that time is 32,000 riders" at https://www.reviewjournal.com/local/traffic/las-vegas-approves-68-miles-of-underground-transportation-tunnels-2874498/ https://www.reviewjournal.com/local/traffic/las-vegas-approv... , while https://glasgoweyesmagazine.com/why-is-the-glasgow-subway-so-small/ https://glasgoweyesmagazine.com/why-is-the-glasgow-subway-so... says the Glasgow subway can handle 30,000 passengers per hour. That RJ article also comments that the decision to extend the line was strongly influenced by political pressure: "Las Vegas Mayor Carolyn Goodman isn’t sure the project will ever come to fruition, but voted in favor of the extension anyway, due to the urging of the various resorts and other entities in downtown." "“I am one who just does not believe will come to be, certainly not in my lifetime,” Goodman said during Wednesday’s meeting. “Hopefully in the lifetime forthcoming. Moving three and four people at a time does not get this on … I want more accessibility, I want to move people more easily and I’d like it to happen immediately, because we need that movement of people now.” As you seem to suggest at https://news.ycombinator.com/item?id=38690234 https://news.ycombinator.com/item?id=38690234, Las Vegas isn't paying anything for the system, so it's not like a bad decision has much risk for them. That makes it hard to accept your view that the decision in Las Vegas was based on technical merit. > Myself and other commenters are pointing out that point-to-point is the user experience, no stops between start and destination, not the layout of the tunnels, which looks just like a subway system But getting that experience requires NOT designing like a subway system but rather like a highway system because you need more space/lanes to handle passing, and more space dedicated to inter-car separation. That's why I've been saying that it isn't obvious that it should be cheaper.
