He's raced super cars at super speeds, but the thing that finally rattled The Stig was our very own Matty McLean.
The Top Gear star - whose real name is Perry McCarthy - took Matty around the track on Breakfast during the week, prompting a bit of motion sickness.
But then he made the mistake of swapping seats.
It didn't start well as Matty asked: "How are you finding this, Perry?".
Watching back in the Breakfast studio, Jack Tame answered for him: "You know when you can see the whites of the eyes of The Stig then that's a moment to be concerned."
By the time they reached the end of the track, Perry was shaking and in a hurry to get out of the car asking, "Is it too early to start drinking?"
But we reckon Matty did a pretty good job! Check out his Fast and Furious moment in the clip below.
