I like driving in Italy — but not in Naples— never again. I agree in the countryside it can be necessary. One has to be aware that going to places via car like Siena or Assisi one will have to park outside the city walls for a day trip— one can stay in certain hotels that will register guests and their cars to allow access in the center. In Siena for example I was only able to exit and enter at one entrance — make a mistake and expect a ZTL charge. And with a larger car that can hold several large suitcases it can be a challenge to park and navigate the narrow older streets.
