A prisoner escapes in a car through an empty barren land. Suddenly he realizes that the steering wheel is broken: it does not turn right. The car can only travel in two directions: straight ahead and left. He is at point A and is moving towards the arrow. How does he drive to his hiding place on X on the other side of the lake without going beyond the bounded area shown by the dotted line? He cannot turn around, get out of the car or cross the lake.
