Norris dobbing in the mercs when they both ran off the track in the wet and joined "unsafely" after. Then again there was quali (I think) where he complained about Lewis swerving to the right to get ready to start a lap, which even Zak said live on air that nothing will come of it.
Have to wonder about the mentality of Lando. He seems very negative and moans a lot about things he can't even control. Seems often annoyed in his responses to his race engineer.
I think he needs a firm hand in terms of management, and the team deciding thing like the medium tyres for him. Oscar seems more cool under pressure and is clear, quick and calm with responses. i.e. "yes, yes, medium is best tyre".
