Faith Dickey risks life and limb every time she walks across a slackline but pulling off this stunt is beyond crazy.
The world record highliner was filmed walking across a cable strung between two speeding semi-tractor trailers before they reach an upcoming tunnel and the line snaps.
The stunt was performed live on an empty mountain road in Croatia for a Volvo truck promotion.
Besides keeping her balance on a swaying line, bumps in the road and battling the oncoming wind, Dickey has that tunnel wall to respect. You can see her give it a nervous look as she approaches the tunnel.
She was successful after a few rehearsals. A few?!
Safety tether or not, if a highway railing didn't kill her, one of the 18 wheels probably could. Pretty spectacular in every way.
