Car computer crashes, literally.

WeThree writes " A German couple drove their BMW with great confidence under control of its computerized satellite navigation. Indeed, they drove it past a stop sign, down a ferry ramp, and into the Havel River in Caputh, near Potsdam/Berlin, Germany. The computer system reportedly neglected to tell them they needed to wait for the ferry." Looks like it's not quite ready to put in autodrive mode yet.
