Lewis Hamilton called for action to change "archaic mindsets" after a racist remark about him by Brazilian triple champion Nelson Piquet emerged on social media, triggering widespread condemnation.
In a Brazilian interview on YouTube in November, Piquet, 69, used a racial slur in Portuguese when referring to the seven-time world champion, when commenting on Hamilton's British Grand Prix crash with Max Verstappen.
He also said Hamilton had "played dirty" in the incident. Piquet's daughter Kelly is Verstappen's partner, and the comments resurfaced as the drivers prepare to return to Silverstone this weekend.
