I think most of Q3 cocked it up to be honest, but particularly Hamilton who couldn't even do the yellow flag trick properly
A turn one collision is a good point, as there is previous for this here, I recall a certain Michael Schumacher trying to force a restart back in 2000 by parking his broken Ferrari across the track *rubs chin.
As a Williams fan, I'm hoping for a good clean race with no safety cars.. as I feel this represents their best chance of converting their qualifying result into a podium. The safety car period
(and pit stop problems) really hurt their race at Montreal because it meant that the one stopping cars were much closer to them at the pit-stop window, and hence they lost track position and time.
I think ultimately, assuming there's no reliability glitches this time the Mercs will move through to the front, Rosberg first and Hamilton after dispatching the rest of the upper midfield, the natural car advantage of the Merc ought to see him able to overtake. Rosberg ought to be able to maintain that to the end but I also have a feeling that Hamilton will hunt him down and there'll be some more wheel to wheel and brake locking stuff going on.
After that I expect Ricciardo to be mixing it with the Williams, Alonso and Hulkenberg may be able to go longer on the tyres, so this could create chances for them, and likewise Vettel and Perez as they both need an alternate strategy to try and get back into the game.
