If a take a short cut through the woods mine tells me off in
an imperious tone, idiot "You are not on a road" how do you
expect me to direct you when you are lost?
Similarly, dummkopf ! "You are going in the wrong direction".
It's also good at finding unnavigable farm tracks that take
you across ploughed fields.
Colleagues say theirs is good at taking them over cliff edges,
and telling them to turn right in the middle of a flyover.
