If you ever went 4x4 driving, you use driver / passenger to indicate the direction someone has to go to. This is because the navigation often is done from someone standing outside the car, where using left/right can be rather confusing.

In UK a [experienced, older?] driver gives another driver instructions with "right hand down" and "left hand down". That is, you give directions to move the steering wheel.

I've the vaguest recollection that sailing/steam boats used to say which side to move the wheel towards to steer; that begging opposite of the way the boat will go??
