even a taxi or ride share may come out cheaper than public transit too.
Part of it is public transit like trains and trams have to maintain their own infrastructure.
Not sure about buses, I would guess these are way cheaper to operate. In many parts of the world they are cheap, private and profitable, e.g. https://old.reddit.com/r/Detroit/comments/1l5pt2a/detroit_th...
Not GP and I don't know anything about this either, but I found this:

Anecdotally, I used to take the Greyhound a lot and everyone on them is either a student or somewhat homeless, e.g. they just lined up another friend's couch to sleep on for a little while.
