Even if everyone bar Mia here agree on the crash being Nico's fault, I also think that both this crash and the ones in Barcelona and Spa wouldn't have happened had it not been Hamilton driving the other car. Quite a few drivers are overaggressive in their defending and put their cars in positions where the other driver has the choice to take evasive action (often needing to drive out of the track) or crash. Lewis does not seem to be a huge fan of yielding whenever other drivers' defending is excessive or even dirty - so that's why we've got crashes. However, if you rewatch this season's races, you'll find lots of scenarios where the defending driver doesn't leave one car's width, which leaves the pursuer angrily gesticulating at the car in front - but backing off.

This is not to take the blame away from Rosberg - his driving was dirty. I'm just saying that it's not as uncommon amongst the drivers as we'd like to believe.
