Motorsport lost oneof its most enigmatic stars this month when Carlos Reutemann died at the age of 79 after an illness. Argentina’s greatest racing driver after Juan Manuel Fangio won 12 grands prix from 146 starts from 1972-1982, famously choking at the Las Vegas finale in 1981 when he had the title in his grasp. No one at Williams ever did understand what happened. But Reutemann should not be defined by that.
