I'm not even sure what Hamilton said on the radio, Brundell said he wanted to retire but it sounded like he simply said the word tyres and the rest was barely hearable, I figured he was talking about which tyres to go onto.
Assuming he didn't say retire as I have no reason to think he would, in any race you can have a crash, bad tyres, slow cars, rain, anything, at that stage he had every chance of taking advantage of any problems and jumping into the points. It wasn't a massive chance and its not like a decade ago when 10 guys not finishing was fairly common, but it was possible. At the end of the race it wasn't possible and they did exactly what Button did earlier this season, then Button gave up 1 or 2 points to retire and be able to change the car before the next race without penalty, new gearbox I think was said at the time.
Same here, at that point it was game over so they pitted Hamilton and will likely make changes otherwise not allowed before the next race, gearbox or something else, don't approve of either but there you go.
As for the unlapping, it was nothing short of hilarious, completely allowed and Vettel's own fault, he didn't defend well and gave him the chance. Clearly they wanted to hurt Vettel and Alonso's race if possible, and its another time that Hamilton helped Button gain places by harrassing the guys infront, he just doesn't usually do it from so far down. The really stupid thing is, they could/should have put Hamilton on "ruin the tyres uber laps" when Alonso pitted, and pitted Hamilton and try and get him ahead of Alonso again to again help out Button. Instead they waited too long, pitted him anyway and he was too far behind to help.
Hell if they'd kept an eye Alonso they could have pitted the same time, maybe done a stunning stop and got out ahead, but could have had Hamilton do "who cares about tyre life" laps vs Alonso's "got to get to the end of the race" laps.
Hamilton cost Vettel, no question, Hamilton helped his team, no question, Hamilton did nothing wrong, no question, Hamilton got the worst of the luck again.... nothing new.
I can't believe the front 2-3 guys hit that debrie so hard and hit so much of it, and Hamilton is the one that gets the puncture.
