Head Navigator 

A head navigator is somebody that cocks their head when turning a vehicle. Try walking around a corner with your head cocked. It fucking doesn't help, so why the fuck do it while you're driving?

Check out the head navigator making the right turn. Notice the head cocked to the right at 30 degrees. The fucking idiot must figure the centrifugal force of their cocked rock-head will assist with the turn somehow.
