Rail is good and dandy. You can move large amounts of cargo, large numbers of passengers and do it for cheap. This works really well on the scale of Japan with bullet trains for example.

More ways to commute for people is good; you never know when your car will need repairs and you can't afford/can't find/don't want to spend the capital on a rental.

A subreddit like "fuck cars" sounds stupid because they would appear to believe that cars are bad, but that's retarded. Doesn't mean rail is bad.
