Looks like yet another damp weekend, and this one will decide the Drivers' World Championship.
The Interlagos track has been relaid so the rain has brought oil to the surface, which is making things nice and slippery.
Nakajima has replaced (the newly retired) Wurz at Williams.
Apparently Hamilton, Button and Sato are under investigation for using 2 sets of wet tyres in the morning practice session.
McLaren has been fined 15,000 euros (£10,445) for its breach of the rules governing tyre use at Interlagos on Friday – but world championship hopeful Lewis Hamilton has avoided serious punishment.
