In reply to dmatth:
Been to Sicilly before? If not, you are in for a treat, driving is.... how to put it?... adventurous? Especially in Palermo itself, it is pretty hardcore. My recommendations - make sure you are alert and well-rested before driving in/through the city and make sure you really use your mirrors all the time, drivers in Sicilly are expected to give way to vehicles from in front, behind and both sides, sometimes simultaneously. Road signs and markings are only vague suggestions and your number one aim is to fit in with surrounding traffic rather than the surrounding regulations.
Also, if you get pulled over, all occupants should put hands out of the windows and wait completely still for the police to approach. The police are just as scared of you as you are of them and they are the ones with the guns. Probably drawn.
Have fun
