Formula 1 drivers have criticized the president of the sport’s governing body, the FIA, and asked to be treated like adults in an escalating row over swearing in news conferences.

FIA president Mohammed Ben Sulayem said the grid’s stars had a responsibility to stop swearing on the radio and that they should not act like rappers.

Red Bull's three-time world champion Max Verstappen was punished for his language in a news conference at the Singapore Grand Prix in September.
