Vettel used up all the space he could to block
He clearly could have held left more but that would have meant Hambone would have taken #1 spot.
Vettel closed the gap when he should have yielded after going off track

His angle changes after he comes back on the track, and it changes away from the direction he was going, to move closer to the wall then he would have if he had kept his steering wheel straight.
