I usually vacation in rural areas and it wouldn't make sense to build train routes there, but even if I were going somewhere by train, I would still want to have a car once I arrived. (A place like NYC might be an exception because there's nowhere to park unless you're staying on the periphery.) I suppose I could rent a car at my destination, but I think having to do that would be more expensive and less convenient than just owning a long-range car.

I've heard Europeans talking about how great their rail network is, but I'm not convinced. I've never used it myself so maybe it's better than I think it is, but here in the USA I prefer to drive even if there's a train straight from where I am to where I'm going.

(I know there are environmentalist arguments in favor of trains, but I'm not addressing those here - I'm only talking about what I want, not what I might be obligated to do.)
