In Finland, everything is wheelchair-friendly from our Helsinki metro, to trains, to buses. I am kinda shocked to read Americans think it's not important to allocate the money to enable those with limitations to live their lives as freely as they, the able-bodied do. The mentality "it does not apply to me, why should I fine two fucks?" is all too common in the American ethos. Quite pathetic really.
The Helsinki Metro was built in 1982 and has 17 stations, of which 6 are underground. The New York City subway system has 472 stations, almost all of which are either underground or above grade. It was first opened in 1904. The difference in cost and complexity of providing universally accessible service is massive.
