You should try being a marshaller. The number of pilots who think the aforementioned both hands moving at the same time means` head straight for the marshaller, no matter what`s between me and him` is amazing.
What you must remember is this:- if you are being marshalled you must obey the instructions of the marshaller OR STOP. If he says turn, you turn. If you don`t think it`s safe , you stop. If you carry straight on and hit something, whose fault is it?
