Although it was undeniably a dangerous move, you cannot be sure it was as close a thing as the picture makes it appear. Long lenses make even very slight angles inportant. Looking at Rubens, it appears that his car is still heading towards the wall. If that were the case, he would have crashed. The only reasonable explanation that I can reach is that a camera angle make it appear closer than it was.
In any event, I already said he (MS) should be suspended for at least one race, and Heidfeld be brought in as a replacement.
