Watch this: http://de.youtube.com/watch?v=7dKvZE0iuU8 At 0:06 they touched. Bourdais' car front end hit Massa's car rear end. You can see how the STR twitched while the Ferrari started spinning. Given the position of the cars at that moment Bourdais has been overtaken and should have yielded the position. He wasn't squeezed out of the track either, and at the moment they touched he was close to the middle of the track. IMO the Frenchman carried to much speed into Turn 1 given that he had a car on his outside. His mistake and his penalty. I tried to be as objective as possible given the material we have at our disposal.
