Formula One's world champion-elect Lewis Hamilton has been scarred for life by racist abuse that he experienced as a young driver, Mercedes team chief Toto Wolff said on Friday.
"When Lewis was younger he was the only black kid among the white kids, and I know he was racially abused on the track," said Wolff.
"If that happens to an eight-year-old, or a 10-year-old, it just leaves scars that will not go away."
"We have to acknowledge that we are not very diverse in Formula One and I have certainly learned through Lewis to accept that it is difficult to overcome discrimination from time to time."
