I disagree with this on the basis of "tragedy of the commons"[0] For every person acting in their self-interest, it's usually cheaper and more efficient for them to use their car. However, using their car has a cost of congestion (and a cost to the local and global environment) that is borne by everyone: if everyone makes the same decision, then everyone suffers quite badly and is still more constrained because now the public transport option is unmaintained and even worse than before. A "Prisoner's Dilemma"-type Nash equilibrium has occurred. As such, it's important for government to incentivise public transport (which they generally do, as it stands).
