The stewards’ report says that he had failed to complete the overtake at T1 and had gone into T2 too fast. Whilst HAM could have left more room they felt it was predominantly VER at fault.
So, paraphrasing, I am launching into this corner like it or not, if you are in the way we crash. It’s like a Verstappen motto.
On the refusal to give the place back, there is some suggestion that this was payback for Monaco, where it is claimed that PER deliberately crashed at the end of qualifying to prevent VER improving his position. Even if any of this is true, firstly PER had given him the place to go after ALO on the understanding that he gets it back if this doesn’t happen. And regardless of what went before, VER has the driver’s championship and RBR have the team championship, so what exactly does he have to prove by petulantly ignoring team orders and stiffing his team mate? And doing it over public team radio too. A childish sense of entitlement and getting his own back? That’s the sort of behaviour that’s needed in F1. Real heroic, inspiring stuff.
