In what has to be one of the most insane automobile stunts of all time, The Stig from the BBC show “Top Gear” went bungee jumping… inside an F1 car.

At the Top Gear Festival in Durban, South Africa, the helmeted character from the popular TV show climbed inside a Lotus F1 and plunged 300 feet.

See if you can watch the video without holding your breath.

While some commenters on the video’s YouTube page claim the stunt’s a fake, footage from the event shot by a fan and spotted by Joe.ie, below, seems to prove otherwise.
