Mercedes was infuriated by how the final laps of the race played out after Nicholas Latifi’s crash triggered a Safety Car period.
Under normal circumstances and according to Article 48.12 of the Sporting Regulations, all lapped cars should unlap themselves before a Safety Car restart so that the field is in positional order when racing gets back underway.
Mercedes also protested Verstappen under Article 48.8 of the regulations, which says that once the Safety Car is returning to the pits, no one is allowed to overtake the lead car.
