Boy, was he glad that bag had come off.
Peter came to the conclusion that because the reason the bag/paper stays on the visor is because the wind flow caused by ones forward motion holding it there, a turn of the head to the side means that there is every chance the wind will assist you in tearing the obstruction off.
Failing that, Peter decided, he would lift his visor. This will both change the wind flow and hopefully send the bag away and also open up a window of view he hoped.
