Mercedes say they'll consider dropping Lewis Hamilton or Nico Rosberg if their two drivers cannot race together cleanly, after the two drivers collided at the Belgium Grand Prix at Spa.
Mercedes say they'll consider dropping Lewis Hamilton or Nico Rosberg if the pair cannot race together cleanly.
The ultimatum from Mercedes sports boss Toto Wolff comes in the aftermath of the drivers' collision in Belgium.
Mercedes have taken disciplinary action against Rosberg for the collision at Spa last month for which Rosberg has taken responsibility and apologised.
Meanwhile, Hamilton has queried the FIA's decision not to investigate the collision with Rosberg.
The governing body decided not to look at the incident again despite it emerging after the race that Rosberg had told his team he had known the two could crash.
Hamilton said: "Can we race a lot closer and if the other guy is out of the race nothing will happen? Or if it happens again will there be a penalty?
"We are always asking to be able to race. But there is a fine line."
