@ Gnome: The last time I was in Norway (it's a long time ago), there were a lot of really long tunnels without any lights in it. Do they still exist? Because it was really special do drive through them. Here in the central of Europe, most tunnels are illuminated.
I think most countries have some very nice B-roads, where you can have the thrill of driving them. Certainly in the mountains you can find a lot of nice roads.
The Stelvio Pass in the Alps is commonly know as a nice road, although it's very twitchy and narrow with it's endless hairpins.
