Mercedes motorsport boss Toto Wolff suggested team orders might have to be introduced after Lewis Hamilton and Nico Rosberg collided on the last lap at the Austrian Formula One Grand Prix.
"We're looking like a bunch of idiots and it's disrespectful to 1,500 people who work their nuts off on the cars," he told Sky Sports after Hamilton's victory.
Stewards later imposed a 10-second penalty on Rosberg for not giving Hamilton "racing room," and reprimanded him for continuing with a damaged car.
The penalty did not change his fourth-place finish which saw his lead in the drivers' championship reduced to 11 points.
Mercedes have given Hamilton and Rosberg freedom to race against each other, with Hamilton winning the last two F1 titles ahead of Rosberg. But the team-mates have been involved in several shunts, and both went out after collided early in this season's Spanish Grand Prix.
Wollf did not explicitly pin the blame on Rosberg but said he had been experiencing brake problems and that it might have been more sensible to accede to Hamilton.
Asked if Mercedes could impose team orders, he replied; "What I am saying is this is on the table because maybe that's the only way we can manage the situation.
"I hate team orders but if every race ends up in a collision between team-mates, it's not what we want.
"If you are losing a one and two and finish one and four and lose a lot of points, that's not nice."
The Mercedes team supervisory board chief Niki Lauda said Rosberg had tried his hardest, with brakes that were no longer fully functioning, to prevent Hamilton overtaking.
"Therefore it is primarily his (Rosberg's) fault," he told Germany's RTL television.
