I know as much about F1 as Daytona does about diplomacy, but even I knew who Niki Lauda was, what I didn't know until this morning was how quick he returned to F1 racing after the crash, that takes courage.
Like so many of his generation and into the 90s, Niki didn't necessarily agree with making F1 super safe from danger. Despite his own appalling crash. He accepted the risks, and believed that you don't start racing unless you can accept some level of danger.
He also gave away all his trophies for race wins, in exchange for a lifetime supply of free car washes. He was a character.
