People like lists, 10 that, 10 these and so on.
This is my list :
1-First race of the year, can't judge much from anything.
2-First race with new rules, qualifying, engine specs, so you can't expect much from anyone.
3-First race in new teams for some drivers, you can expect some performance, but not much.
4-Driver performance/Car performance/Team performance are mixed in the race, so you can't entirely blame the driver, unless where it is clearly shown.
Massa : He made a mistake, pushed a little harder where it should not, that'll serve him as a lesson. He could make the pits and back to the race in a position to fight for the points or even a podium. But there was a team mistake... or was it a machinery failure ?
Barrichello : Gear problems, said so. Bad luck, then. But people think he can beat Button fair and square, well, it's something we're about to see... or not see.
