>good luck speaking English on the German countryside.

It differs, in generally people either speak it there, and then do so reasonably, or they absolutely don't speak it, not a single word.

This is quite different in The Netherlands. In Amsterdam people in shops etc will often address you in English and are rather fluent, but even in the most remote villages of the Dutch countryside everyone speaks some amount of English. It may be with a very heavy accent and not fluent at all, but generally it's enough to at least have a basic conversation.
