I don't believe that Spaniard drive like Psychos, nor do I believe you are stupid or crazy for wanting to drive through Spain. It is a beautiful country and seeing it through the window of a Boeing 727 would not do it justice. However, I don't think there is a country in the world that will rent a car to anyone under 21 years of age. In fact, many have a min age of 25! As they say, you may be S.O.L.
