Description from the site:

Being a co-driver is a pretty thankless task. With little recognition, it is often the driver who gets all the glory; not in this rally team, however…

The co-driver here is the epitome of dedication to the team. When the throttle breaks, he jumps out and sits on top of the engine. With the driver leaning out of the window to see past the raised bonnet, our plucky navigator sits out front, manipulating the throttle with his hands.

What a hero. What an incredibly dusty hero!
