Another point to make was that graziano was a long time friend of the hogan's, live with them on and off because of the rough relationship with his own family, and even wanted to be part of nick hogan's "racing team". When it comes down to it, i highly doubt that graziano was like "hey don't race that viper". If he was that concerned, he would have at least put his seatbelt on. Look at nick hogan. He was wearing his seatbelt and only substained minor injuries. If graziano would have been restrained he most likely wouldn't have recieved such a severe head injury...
