Rosberg was on corner exit down a straight, and from memory his steering wheel was turned right the whole time. Its not like he was running straight, checked the move and reacted, he knew he was in trouble mid corner was was on defense from there.
Verstappen has done Belgium, Hungary, Suzuka and Germany. I don't feel it's right, even if it's not written in the rules. Funnily enough, in Germany, Rosberg got the penalty as his resulting overshoot of the corner ran Max wide and off the circuit. I think he needs to be talked to before there's a more serious accident
