Going back on this after rewatching it constantly during the race everytime the highlights popped up, I'd blame both drivers for the 55/90 incident. Yes, Marciello wasn't exactly at the right place, but Cioci turned in to La Source as if he wasn't even there. Keep in mind at the time Cioci was 8th and Marciello was 2nd, so he was getting lapped, blue flags were waved and he should have let him past since they weren't on the same strategy anyway. The only thing that would have changed in the end had Cioci let him past is that the Ferrari would have made it past Eau Rouge. Marciello got agressive, Cioci got selfish, and contact was made. René Rast and the #1 totally deserved the penalty, from the onboard you can see he's not even past the #90's door upon the point of contact.
