>>507729181 (OP)Trains fucking suck, especially in comparison to cars.
Cars give you privacy, the ability to go anywhere you want, choose your stops, and for longer trips are just as affordable.
Train stations are a fucking confusing mess, the one help desk (which is mandatory for finding out which train is yours) is always behind a huge line, or fucking closed. Half the time there's either no working toilet or no free toilet, there's no AC in the station and sometimes you have to wait hours just to get onboard your correct train.
America doesn't have trains because it doesn't need them. Cars do everything trains do and more, in a more timely and convenient matter.
Plus, where would you even go on a train in America? From New York to Baltimore? Cleveland, Ohio to Colombus, Ohio? At least in Europe trains can take you to another interesting and different place within a few hours normally.
