Video: Ballsy Parkour pros perform stunts on moving cars…

We've seen plenty of daredevil Parkour runs in the past - such as this frightening GoPro footage - but we're not sure we've ever watched anything as wonderfully dangerous as this.

Parkour pros William Spencer, Alex Duong, Daniel Ilabaca, Josh Yadon and Bart Baker have (seemingly) teamed up with Fiat to advertise the 500 Abarth with a range of stunts on moving cars. We see the group jumping on, over and in the speeding vehicles without a care in the world, with one even trying out a tightrope act. It's seriously impressive, but we doubt their mothers would approve... The stunts you see above come from a short film titled Midnight Mayhem, which you can watch in full below...
