That's what I saw too. He squeezed the inside car. Of course he blames everyone but himself in the post race interview and even throws in the excuse that his teammate was beside him so he couldn't see mag on the inside. That doesn't excuse turning in blind.
Pretty dick move to also try and throw your weight as a veteran and blame it on the inexperienced drivers not taking due caution.
It was Massa's fault. You can't make a dive like that in the first corner of the first lap of a race. Massa has been in a lot of incidents this year, most not technically his fault. He just doesn't seem to be able to drive around trouble like Alonso or most of the other experienced drivers though.
I had high hopes for Massa this year but Bottas has deservedly outshined him.
