Niki Lauda managed to survive for 43 years (and two more world championships) after being given the last rites. Not at all bad for a guy who died twice in the aftermath of that horrible accident.
I had the privilege to meet him (briefly) once at Goodwood, he did indeed look like a rat, he had piercing, inquisitive eyes and an intimidatingly sharp intellect. As a driver Niki was not only quick, but he had an unrivaled understanding of the technical aspects of his cars, his tactical ability saw him beat the arguably faster Prost in 1984.
You have to take Rush with a bit of a pinch of salt, apparently Hunt and Lauda were quite close even during their 1976 battle. Legend has it that they had interconnecting rooms at Suzuka in ’76 which prompted Lauda to goose-step into the adjoining room and announce “today, I vin ze world championship” much to the amusement of Hunt who apparently had female company at the time.
Perhaps this t-shirt sums him up nicely – Lauda wearing a James Hunt T shirt.
