Pointing his car into a pitwall?
That's a weak diversion. Rubens was headed for turn 1, nothing else.
Maybe you are deceived from the perspective view.
If you mean Rubens was going to pass shumi on the right then yes.
Rubens can jam his car anywhere he feels. Even brundle was saying that Rubens should jam his car up shumacher's inside blindly and let shumacher handle the rest.
The attacker can weave and dive brake test, as long as he is the attacker, it shouldn't change what the defender is required to do.
Check out Hamilton barichello 2009. That's a text book wall move.
