Hamilton's driving at the start was scandalous. He could easily have collected several cars. He completely cut up Kovalainen and could have collected several cars. Yeah, he didn't hit anybody, but that is not the point. He could well have done so. I don't know what he was thinking. Massa's driving was sinful. He deliberately took out Hamilton and should count himself lucky he only got a drive-through penalty. His attempt to "overtake" Bourdais was also a farce and he passed Webber outside the track, so he must get a five or ten-place grid penalty next weekend.
I basically agree with all of this except the Massa being deliberate part.
Massa's move on Webber was silly and dangerous, and he definitely needs to be at least investigated for that if not penalized altogether.
Kimi says one (or two) of the McLaren's hit him and he incured damage in the front because of that. HAM gained a racing advantage from a mistake and a penalty was due. Unfortunately for him there really is no penalty with less impact than a drive-through, so the stewards didn't have a choice.
Whatever happened to "tough but fair?"
