>> The Elizabeth Line was unbelievably expensive to build; that's how the UK did it.
Fair. But what is also expensive is every single citizen taking $100 Uber rides to the airport, like in NYC. In NJ, the transit service has become so volatile and sporadic and opaque that people have reduced NJTransit use for Newark airport in favor of simply driving.
That cost doesn't show up on government books, so we can pretend it doesn't exist. The joys of decentral planning.
