Complex Says: Want to get a better idea of just how fast Formula One drivers go? During a practice lap for the '09 Hungarian GP, Massa was driving when a spring from a fellow driver's car hit him in the helmet and knocked him unconscious. He drove directly into a barrier and missed the rest of the races in 2009 with a serious head injury that could have killed him.
