Well in the last race Hamilton got pole with a lot more fuel, but it was really wet so who knows what fuel he has now. I've seen the video of Hamilton slowing behind the safety car, to me it looks like he got too close to the SC and wanted to give it some distance so he would warm his tyres. It was really the fault of the conditions and poor visability, although Hamiltons stopping moves were a bit dodgy, I don't think they broke the rules.
