Yes my country is small, but we drive all over Europe, and the German Autobahn is an ecosystem that requires a very well handling car. My 2 litre French car handles beautifully in the mountains, and has no difficulty crossing the Alps. As for urbanization rate, almost no country in the world is more urbanized than we are. But you are quite right that the driving environment is very different. Having driven a lot in both the US and Europe, I guess the biggest difference is on the one hand the lower speeds and and wider roads in the US, and on the other hand the terrible road surfaces in many parts of the US. We experienced the same two years ago when we rented a small Ford Fiesta on our holiday in Albania. The car handled very well (much better than the small Kia that we rented two weeks later), but it was not properly adapted to the atrocious road surfaces. Next time we will get a small SUV there. Wonderful country to vist, by the way.
