The US passenger rail system is badly mismanaged and offers lousy service. If the network were to be expanded, I'd expect more of the same lousy service.
I like commuter rail and subways in Boston. I wish the parking was better at the railheads, that would encourage use. If I lived in Boston, I wouldn't need to own a car, I'd just rent one as needed for trips outside the area.
Once I drive as far as Boston suburbs, I might as well keep going in. It's faster to cover the final distance by car, and the parking fees aren't too bad, once I subtract the rail and subway fares I'd otherwise need to pay.
Also, I can load all my packages and bags into the back of my car. The subway is really inconvenient for that.
