@ossobuco,
Yeah, my father was an avid outdoorsman and traveler, so we drove and camped from Canada to Mexico- pretty much anyplace that he could go fishing.
Funny you should mention Rome - just left there actually- and did hire a car and drive. On the Autostrade - not very different than the US at all - but in town, I had to keep asking myself, 'Does this road have lanes? And if so - why does no one stay in their lane? It was sort of like semi-organiz(s)ed chaos. But then when you get up in Northern Italy near Austria - the whole ethos changes and everyone is very orderly and follows the rules.
It's extremely interesting how the culture changes within a few hundred kilometres. But then again, that's true in America too - innit? And in England for that matter. I met this girl from 'the north' as she put it and she herself spoke about how different people from the north of England are from those from the south of England. She sounded pretty defensive. I told her I didn't have a preference for northern or southern English people either way.
In general I like them all, but they do seem to like to cling to convention a little more than most Americans I've met- I have to admit that.
