Das Navi

After we left Tübingen, we amused ourselves by turning on das Navi--our rental car's GPS navigation system--and then ignoring its directions. To its credit, it didn't raise its voice at all, although when we turned off the highway into Donaueschingen to see the Donau Quelle (the spring that is the source of the 2840km-long Danube river), I expected its default soothing feminine lilt to say something like "ich sagte, links abbiegen, du doofer Idiot" ("I said turn left, you doofus").
