I'm thinking about planning a trip where I drive though every country in Europe. I know that there are people who have driven though every State in the US. There is information online about their plans, the trip, and the time it took. However I can't find much about this kind of thing in Europe. I'm looking for strategies, other peoples attempts, or successes. Driving is not necessary a requirement either, taking the train for some of it would be fine, possibly preferable.
