Sour grapes in my opinion. It's probably that people consider the race pace of the Lotus was so good that they should of out lasted with regard to tyres better than anybody else and that they could always do 1 less stop than the others and still keep doing the times.
Rumours are starting to appear that RBR are bringing a huge upgrade to Silverstone. McLaren as well I also read on twitter.
If Alonso wins this year, he has to go down as one of the all time greats, winning a title in this dog of a car is a hell of a special job. EDIT: By all time great, i mean, being mentioned in the same breath as Prost and Co. He's already a great.
I've all but given up on predicting this season so far! But I think it's already game over, Seb will now pull away come the next few races and the reliability will only improve and I trust RBR to fix this problem completely before the other big teams get this variation.
