Not really that shocking for Max to win, many believed that Perez could, because Perez started at pole position and Max was 9th so everyone assumed Max wouldn't really be getting the win today. But looking at his pace on practice runs and the qualifying results before the red flag, dude was faster than anyone else there. Maybe he found the ideal racing line better than others, maybe his car was better than even Perez's car, whatever the reason was, he ended up being faster before the race as well, and easily showed that during the race. I guess we could start congratulating him on his championship for a third time already. He looks like the guy who may retire for a year or two when he is young and come back later on, that just feels like he is too easily winning titles. I doubt he would go for 8 titles, he would win maybe a bit more, go race some other thing, and come back later on to keep on winning titles again, or maybe on a much worse team to just have fun.
Max showed that he is a mature driver now completely different when he was crashing to his team mates and every one near him not that many years ago.In the interview after the race he said it clearly,I stayed out of trouble in the first lap and then I took each car one by one until I clearly was second.He said that they did think a lot about the strategy for these tires yesterday night and in the end it paid off,not for nothing though it was thanks to his extreme bravery,he was doing fast lap after fast lap even when his hard compounds were completely gone after 25 laps which was the winning move for the race.
Perez should have pushed much harder in the first stint but he wanted to conserve somewhat the tires to go and do more laps with them and this was the losing move for the race for him.
