I don't consider it "unsafe", or problematic in any way, that http://en.wikipedia.org/ gets you English wikipedia even if you access it from a German IP, whereas http://de.wikipedia.org/ gets you German wikipedia even if you access it from an Australian IP. There are plenty of websites that will not give you the page you request no matter what you ask for, if they think you should be going to a different page. That's idiotic.
