My take (assuming anyone cares) is that Mercedes gifted the race to Ferrari through poor strategy calls. In the end, they made one more pit stop than Ferrari. The pit stop delta at Sepang is about 23 seconds.
That's all she wrote.
Putting Lewis back out on hards for the end of the race just showed the team recognized they had blown it and were content to have Lewis come second. Can you imagine having all those smart types manning all those computers and crunching all those numbers and STILL getting your sums wrong? How embarrassing.......
