It is a political decision, whether the government wants to pay the costs out of the federal budget. If the government is serious about CO2 reduction and also shifting commute traffic from cars to public transport, this might be an surprisingly cheap option. As the high energy costs also mean increased tax revenue, it might not even be a large load for the budget (and compared to many other things, spending like €10B/year on public transport isn't really much anyway).
