As for Massa going to slowly in Q3. Take a look at this video and tell me where Massa was meant to go when in the traffic? Maybe he was slowing trying to make space when Lewis got all aggressive. Massa did the sensible thing and let the header by before there was an incident.
I'm not rising to the bait today (have to deal with an ISO Audit so bigger things to worry about). Anyway the sun is shining!
David, the answer to your question is very easy.....Massa should have gone exactly where Hamilton went! Once past Massa, Hamilton found a good spot in the traffic and got a good lap time.
