I think that would be a very risky strategy. The last thing you want to be is in the middle of the first lap crazies with a car thats light years faster than anyone around you. I mean look at Massa's record for the year, the Williams is easily in the "best of the rest " category and the entire grid has been using him for target practice. I mean I never was any kind of Massa fan but jesus noone should have to go through a season like his. Then look at the love shared with Kimi and Alonso, Button and Magnussen each trying to secure their seats, Ricciardo sticking it to Vettel at every turn, Maldonado who ever runs the risk of driving like Maldonado. Just way too much contention in the ranks for it to be safe for the WDC contenders to hang out there.
Hamster and Britney need to get well clear of the mob ASAP and let the second tier fight amongst themselves.
