Mercedes boss Toto Wolff has stated for the first time that the squad may have to implement team orders after Lewis Hamilton and Nico Rosberg collided for the third time in five races.
Hamilton chased Rosberg for victory and pounced on the final lap of the race in Austria, but the pair made contact at Turn 2, which left Rosberg with a broken front wing, dropping to fourth.
Stewards deemed that Rosberg was responsible and handed him a 10-second penalty, which made no difference to his finishing position.
The Mercedes duo also collided in Spain, with both retiring, and made light contact on the opening lap in Canada.
"It was incredibly frustrating for the team to see a one-two finish potentially become a double DNF on the final lap of the race - and to see us lose points again as a result of a collision between our two cars," he said.
"We let our drivers race and we trust them to do so - but colliding team-mates is not what we want and this is something that needs to be stopped.
"If we need to reconsider our philosophy, and to take some unpopular decisions, then we must be prepared to keep that option open."
Wolff refused to lay blame on either side, despite the decision of the stewards.
"As for the collision, I am not going to try and put blame more on one side than the other; it always takes two to tango and, as we have said before, this should not happen between team-mates," he explained.
"We will now let the emotions settle before we sit down and discuss our next steps."
