That's why the analogy is so good! The police car and ambulance were the most obvious ones to me (other than the Honda Civic); surfboard and ice skates were much tougher. It shows how we're really seeing things through our own lenses, even when they seem so obvious that no one could conceivably disagree.

Also interesting: the fact that 50% more people described a skateboard being used as a vehicle than a skateboard being carried.
