The Red Bull drivers Mark Webber and Sebastian Vettel remain divided over who was to blame for their collision in Turkey and have vowed to continue aggressively racing each other Monday's Canadian Grand Prix.
Both say they regret the collision that cost them valuable points but were unrepentant about their own actions after ruining their one-two finish in Istanbul 12 days ago.
Webber appeared to be cruising to his third win in a row when Vettel, who was second, suddenly tried to overtake him.
Webber held his line and Vettel crashed into him, failing to finish the race.
Webber recovered to finish third and extend his lead in the championship to five points.
