I think there should be a backward facing camera with a screen in the cockpit, the wing mirrors are almost completely useless, almost just a token gesture. If it had been in the dry it would've unquestionably have been Buttons fault, the Webber incident was just one of those things, schumacher was getting his own back for Monaco. none of the incidents were as bad as LH on Massa at the hairpin, just one of those things that happen in the wet, tht said, however, they were 'unwise' decisions to make, which has always been Hamiltons downfall.
