The worries from drivers about the health implication of breathing in carbon dust during the course of a race weekend emerged after the Austrian Grand Prix when Sebastian Vettel in particular emerged from his car with a face spattered with black carbon.
Vettel said the long-running issue had worsened this season owing to the new brake duct layout, with drivers now not only subjected to the brake dust generated by a car they’re following, but also dust created by their own car.
