1) By all means, NEVER use a turn signal. This is a sure display of weakness.
2) Do not expect a median strip on a major highway. A white line down the middle? Strictly for sissies.
3) In traffic, people will drive up on the shoulder.... passing you & 10 other cars, then cut back in. You shake your fist (but wonder if maybe you should try the same...)
4) If in a hurry, you will inevitably be stuck behind a truck, usually driven with no particular sense of urgency by an octogenarian.
5) If you fly into Naples & rent a car - GET A CAR WITH GPS.
