Valtteri Bottas reveals 'red zone' Cadillac issue that sparked horrifying crash

Valtteri Bottas has revealed how his horrifying crash in the Mexico City Grand Prix was caused by his Cadillac running in the "red zone" for too long with brake temperatures.

Approaching Turn 1 at top speed at the Autódromo Hermanos Rodríguez, the left-front suspension completely gave out, exploding in a way similar to Sébastien Buemi's Toro Rosso in China over a decade ago.
