Really guys, where has the blue car been off the line? Look at that video again and notice that both drivers took the outmost line to drive to that corner because it is a rather sharp one... The one with the camera is fully to blame for that accident, as he tried to force the pass at a place he clearly couldn't do that (I call that "crowbar-passing") and just hoped that the other one would back off (which he didn't, because he wouldn't even thought the white caterham would try to pass there, thus he was caught by surprise for sure)... You can see that the white car driver's passing attempts get more desperate and more aggressive with the progression of this video, leading to this suicidical move at the end...
The only error the blue car made was not being aware of the white car at this corner (which even that you can't really blame on him, nobody would have passed at that corner... well, ok, someone did)...
