In America the train costs as much as a plane ticket.
While this is often true, I think there’s a habit of comparing apples-to-apples, when they are not the same. Getting to/from the airport is often expensive while train stations are commonly in convenient downtown locations.
Driving is cheaper.
Again, I feel like a lot of people over simplify and just go, “My gas is X, the train ticket is Y. X<Y, so driving is cheaper.” It completely ignores maintenance costs and depreciation, which are a lot more than people give them credit for.
