I know where Madrid is and I have lived in Europe and I just read an article in the New Yorker. I even have a spiffy Certificate in GIS. I still don't find it to readily be a good comparison for a mostly American audience. If the point is to elucidate, I don't think it is a great example to use. If the point is to be all superior and imply or emphasize the idea that "if you don't know where these things are, you are dumb," hey, it works well. But trying to make your audience feel stupid is not really a great place from which to start. I mean, unless the point is to be toxic. Then, sure, go with that.
