Bitter all out war - just like the 80s, except the drivers don't have quite the gravitas of Prost, Senna, Mansell, Piquet. In fact, they're increasingly like a couple of kids arguing in the playground.
As with the old internecine battles, nothing is resolved until one moves on. If Rosberg isn't punished by the team to Hamilton's satisfaction then I can see him moving. Isn't his contract up this year?
