Where does Nico Rosberg go from here?

[Bagwan]

No need to apologise, all good. I guess it comes down to this point, is a driver entitled in a situation like that to cut across another driver? To me, I think yes they should be able to as they should be entitled to do anything which should not end up in contact to defend their position. In this case, I feel Rosberg had the racing line, he took it and at the time he took it, there was really no way he could have known it would end up in contact. Danny was coming from off the racing line onto it. In that situation, where the driver has the racing line, if an incident occurs, I think fault should like with the driver coming back onto the racing line. I can see your viewpoint however, and it's really a matter of what stance you take. Maybe both are valid points and, if that's the case, it's just a racing incident.

Both points are valid , but there needs to be a definitive rule that covers even ones as close as this .

And , I believe there already is .
If you look at the Kimi/Valterri cases , all and sundry called kimi an idiot(except Mia , of course) , and that was because he knew he was there and that Bottas was on the curbing already , unable to give more room .

I don't think I ever read any comments that criticized Bottas for not lifting to avoid either contact , and the second contact had Kimi climbing over his front wheel , so it shows that Kimi was ahead .

So , given that the first one had Kimi chastised for not giving space , and the second one didn't have Bottas penalized , it gives us two consistent rulings which both seem to say you need to leave space .

In neither incident was Bottas expected to lift , though , and it might have saved him a collision both times .
Same logic should apply to your example , I think .
