Gas Stations pay for themselves. Otherwise its also tax based.
Still completely free public transport is not a good idea instead of investing in a high quality offering. (Higher Frequencies, Better Vehicles, more dense network). Because People usually take the car because it is more convenient, its always more expensive than public transport.
And in the past, free offerings have just diminished people walking or taking the bicycle, but no shift Car>Public Transit
You mean Like in Tallin, Estonia?

The Countries with a high Share of Public Transport in the Modal Split like Switzerland have one Thing in Common, an extremely dense, Frequent and reliable public Transport System. The price isn't Just that important,
Just because someone has a different opinion than you, doesn't make it "Propagandist".
(I travel exclusively by Public Transport and I would love to have the Same quality as in Switzerland, but here everyone wants stupid cOmPeTiTiOn and lOw pRiCe Bro, and the quality in Germany is horrible. Montpellier is also not great, I've visited many Times for Holidays, and during the day it's okay, but the Tram Service terminates way to early in the evening. The prices were also already very cheap before it went "free")
