Wake up! This is a race!
There was a lots of similar moves in the past some years, and there was no penalties after those...
Barichello also wasn't penalized in Monaco when hi throw out his steering wheel to the track.
Barrichello threw out his steering wheel because he was in the middle of a fast section looking at the wrong direction. Have you ever come to the idea that Rubens is just a human who wants to came out as fast as possible of his car in that situation?
What we saw today was no race. It was a dirty move that could have ended in a very dangerous way. Holy $hit, some people have even posted in this thread, which show that Schumacher tried to drag Rubens into a concrete wall. When was the last time a driver pulled out such a manouver in a battle for 10th position?
