Wow, cool, you ride an airplane directly into an abandoned mineshaft?

Ok, cool. But I don't think your experience would still be very good if you were joined by an additional trainload of people riding 4x4s right alongside you. It'd be time to pave over that canyon so that the people visiting it can park.

And trains aren't mutually exclusive with cars. I might take the train to visit my parents a few cities over, but that didn't mean there wasn't a highway for the moving truck to drive along when I had to get my stuff over to where I live now.

No-one is saying no-one should drive a car. Rather, that the right tool for the right job should be used. In the US, cars are used for a lot more than what they're best at. That you are using them effectively for personal use, is not a reason to also have them used where they aren't as effective (in this case in comparison to trains, large volume transit of people who are mainly transporting themselves between hubs of human activity).

In Tokyo, Shinjuku train station routes 3.8 million people to where they are going, EVERY, DAY.

Interstate 5 in the US, the busiest in the country, does a pathetic 0.75 million a day on its busiest strip. And the cost-effectiveness of trains beats out cars waaay before you hit capacity on such a highway.
