This is about linking major metropolitan areas together, not accommodating those who wish to suburbs. One of the central tenants of this plan is that these stations should be in the heart of the cities (as is done in Europe) rather than a major commute away.

Also, I just returned from backpacking in Europe, where we used rail as our primary mode of transport. Security is minimal; among my three trips on rail in Spain, we never had our passports checked and our bags were only scanned once in Barcelona.
