The L.A. train system (at least when I lived there) had no turnstiles. It was mostly on the honor system. They did have transit cops that would randomly check to see if you had a ticket, but there weren't hundreds of them or anything. You'd see one on occasion.
That's how it works in Europe, at least in cities I've visited (mostly Germany).
If we'd see public transit as a public good, rather than something that's supposed to be a profit center, maybe we could be a little smarter about it...
Yes! In Luxembourg it's just free. All busses, trains, funicular, trams, in the whole country, for everyone.
Great way to encourage less car use, more active lifestyles, and improve quality of life while also helping the economy.
As a small side comment, Luxembourg is beyond tiny, like the size of New York but with a fraction of the people of New York loving it in, and it's also super rich. I'm guessing that makes it quite easy to do things right.
But yeah, public transportation can rock of done right
