An anonymous reader points out an ExtremeTech article that begins: "Historic car races might seem like the last place you'd find modern auto technology. The cars are lovingly restored to their full, authentic racing glory, and care is taken not to allow modern tweaks to improve their performance. Surprisingly, though, both the pits and the cars are crammed with modern technology to help drivers improve their performance. Long-term benefits from tech at the race track isn't confined to racers, though. Researchers are hoping to use what they find by monitoring drivers' bodies and brains, along with the cars, to build better and safer cars for all of us."
