[Top Gear] Who/what on earth is The Stig?
gpt
Some say that he's a rare albino specimen of a secret domesticated branch of the genus *Homo*, that has been secretly bred for speed at the cost of intellect since shortly after the wheel was invented. Others say that modern racing suits are designed to mimic that species' chitinous heads and leathery hides. 

All we know for sure is that he's called the Stig.
