So, in Ireland, which has a historically pretty terrible public transport system, the government has been fairly aggressively cutting fares. A journey which cost me about 6 euro literally 20 years ago (about 9 euro in today's money) now costs 2 euro, transport is free for kids under 8 and extremely cheap for people under 25, and so on. And it has _worked_; public transport utilisation is dramatically up. Now, maybe there's a point where it stops working as you reduce fares. But it's not particularly _clear_ that that is the case.
