There weren't team orders this year, but Perez wasn't really close enough to have team orders involved. But there was also the case of Max flat out refusing to help Checo because of what happened in Monaco.I think this is a reference to last year, at Austin if I recall correctly. This year Max tried (although I think he was playing up for the radio, but have no evidence for that) to help Checo but he just can't keep up. Team orders would be entirely pointless, risky and a loose-loose for everyone.
Can you point to where there were team orders this year and where they were ignored?
This isn't a criticism of Max. All of the RBR drivers do it, and RBR are exceptionally bad at managing it. We can all look at Seb and Multi-21 but in reality that was just one of many incidents. Nobody talks about how Webber consistently ignored team orders, or how Danny was also against them.
It's a rolling theme with RBR. Most teams struggle to manage it. RBR are probably the worst of it.
