Article was about the carbon emission reductions (titled "Germany's €9 transit ticket cuts 1.8 million tonnes of CO2"). Nobody is disputing that more people used public transport when it was almost free. My point was that it's really expensive as a means to reduce carbon emissions. It does have other effects that would be desirable. If it was for me, public transportation would be entirely free for everybody. There is evidence that the cost savings in ticket machine and fare enforcement infrastructure would make this especially appealing due to cost savings.
