Bare in mind that Italians think that only they are allowed to interpret traffic rules as they please (and not foreigners). In traffic foreign number plates have the same effect on some Italians as a red rag to a bull. If you think of it, you are on holiday and the Italians probably aren't. So they may be in a hurry while you are not. Nevertheless most Italians are very friendly and helpful, even if most of them only speak Italian.
And finally, attention for drinking and driving in Italy. As in many other countries driving under the influence (+0,05%) is by law considered a criminal offense.
