One thing that you're bound to see in Italia is three wheeled pickups. I'm not sure why, but Italians love them. Maybe it has to do with the fact that they have the same number of wheels as their flag has colours? Probably not.
I suppose that they're stable and manoeuvrable, especially down narrow alleyways in villages. In any case, you won't just see them if you pop in the DVD of Under The Tuscan Sun; they're out there for real. Regularly.
