With pretty much everyone expecting Max to do something stupid and take them both out..
Can he really? He would have to have the most iron tight excuse ever surely?
I don't think it'll be a deliberate attempt - more just his usual "well it was fine in Brazil" type antics that could have worse consequences if it ends up with contact.
Whilst it's easy to think "he has nothing to lose" - he absolutely does - it's entirely possible to have incident that puts him out but allows Lewis to finish the race anywhere from 1st to 10th and win the title - it's not entirely risk free, so I don't think he'd go for a deliberate bump.
