Teammates Lewis Hamilton and Nico Rosberg crashed out of the Spanish Grand Prix on Sunday when their Mercedes’ collided on the first lap on Sunday.
Hamilton started from pole but was quickly overtaken by his German teammate.
As Hamilton tried to retake the lead, his car ran onto the grass and bumped into Rosberg. Both cars then spun out of control into the safety gravel.
The accident triggered the safety car to come out on the track.
Mercedes’ non-executive chairman Niki Lauda appeared to lay the blame for the incident at Hamilton’s feet.
“It is stupid, we could’ve won this race,” the former Austrian F1 legend told BBC Radio 5 live.
“Lewis is too aggressive. I need to talk to them and hear their explanation and then we will see what happens.”
The pair’s premature exit left the world championship standings unchanged at the top with Rosberg leading defending three-time champion Hamilton by 43 points.
With lots of shaking of heads in the Mercedes pits and race stewards holding an investigation into the drama the race resumed on lap four, with the Red Bulls of Daniel Ricciardo and his new teammate, Dutch teenager Max Verstappen, in the lead.
