Those are some great rides! My two cents is The Road to Hana in Hawaii, it's one lane part of the time. I also like the drive from Denver, Colorado to Grand Junction, CO just for the sheer beauty of it, especially in the winter! I just had a friend do Furka Pass on a motorcycle and he said it was fantastic! Thanks for this post!
