Oh, this could get hilarious if you constantly go off the route. "Where do you think you're going?" "You should have turned left before." "Are you even listening to me?" "I'm not angry, just go back to the highlighted route." "You're not a good person. Good people don't end up here." "Turn back or I will kill you." "You don't even care do you?" "That's it. I'm not talking to you. The talking is over." That would be awesome.
