Some of my wife's family lives in a mid sized village in eastern Germany, and getting from the nearest international airport to their house with public transport is literally a 6 hour affair (followed by a 4ish km walk) and if you miss any of the connections, you're not making it there that day. By car it's a 90 minute drive on nice roads.
