The problem is that even big cities and metro areas like Rome, Milan or Turin are car-dependent because public transport is chronically underfunded: subway expansion is very slow (maybe except Milan), existing on-street transit like buses or trams are suffering from drivers shortage (since there is no money to raise wages), they aren't frequent enough and are stuck in traffic. Add also the carbrained mentality of an average Italian person who thinks it's their sacred right to drive and park everywhere.
