Bill Simpson has probably saved more people's lives and protected more limbs in racing than anybody. Years ago, he set himself on fire to prove the racing suit he designed would protect drivers from their biggest fear. He believed in his products that much.
In July 2001, Simpson resigned from the company he founded after a NASCAR investigation claimed the failure of a Simpson seat belt contributed to the death of seven-time Winston Cup champion Dale Earnhardt.
Simpson received death threats. Bullets were shot into his home in Charlotte, N.C. His tires were slashed.
Simpson is back in business designing helmets and safety harnesses. His new company is called Bill Simpson's Impact Racing.
