Lewis Hamilton is using his voice to highlight racism in Formula One (F1), Bleacher Report reports. He spoke out after a clip of former F1 driver Nelson Piquet calling him a racial slur resurfaced on social media.

Piquet was discussing an on-track collision in last July’s British Grand Prix when he referred to Hamilton as the Brazilian equivalent of the N-word. The former F1 driver argued Hamilton was in the wrong for a first-lap crash with Max Verstappen, who was forced out of the race after starting on pole. Hamilton was given a 10-second penalty and won the event.

The clip of Piquet’s use of offensive language resurfaced as F1 returns to the U.K.’s Silverstone Circuit.

Hamilton addressed Piquet’s remarks on Twitter, saying that “archaic mindsets” are still prevalent in Formula One today.

“It’s more than language. These archaic mindsets need to change and have no place in our sport. I’ve been surrounded by these attitudes and targeted my whole life. There has been plenty of time to learn. Time has come for action,” he tweeted.

According to the Daily Express, both Mercedes and the F1 have issued statements on the incident.

“We condemn in the strongest terms any use of racist or discriminatory language of any kind,” Mercedes shared. “Lewis has spearheaded our sport’s efforts to combat racism, and he is a true champion of diversity on and off track. Together, we share a vision for a diverse and inclusive motorsport, and this incident underlines the fundamental importance of continuing to strive for a brighter future.”

The F1 noted that “discriminatory or racist language is unacceptable in any form and has no part in society.”

Hamilton has been working behind the scenes to make F1 a more racially inclusive place. Last year, he expounded on his efforts.

“I’m having conversations, trying to hold people in the sport more accountable,” he said in April 2021, The Guardian reports. “I’m constantly sending emails, I’m constantly on Zoom calls with Formula One and challenging them like they wouldn’t want to be challenged.”

In July he gave F1 their flowers, explaining that things are changing.

“I felt for the first time that I didn’t stand alone in the sport. Because for the other years, or the other 27 or whatever years I’ve been racing, no one would ever say anything,” Hamilton said during an FIA press conference before the Hungarian Grand Prix, according to Motorsport.com.

The Mercedes driver is also improving opportunities for Black and brown people in other industries. As Blavity previously reported, he bought a table at the 2021 Met Gala for up-and-coming Black designers. Blavity also reported that Hamilton’s foundation, Mission 44, joined forces with Sky UK to tackle “the issue of racial exclusion that Black children face in the U.K.”
