Lap 15: under safety car
Then carnage in the pit lane

Rosberg wheel comes off in the pit lane and he pulls out
All the mechanics dodge the bouncing wheel
Renault lollipop fella is distracted by the wheel
Renault's Kubica pulls out in to the incoming of Sutil in Force India in the next pit lane
the force India pit crew pumping up their chests giving it large at Renault's crew.
Well done to the Sauber crew for staying calm when a Mercedes wheel was hurtling towards them!
I won't be surprised if Mercedes get a huge penalty for that.
Rememeber Renault were nearly suspended for Singapore cause of Alonso's tyre!
