The first thing I did after nearly having a heart attack watching this stunt was to followup on the differences between the different types of tightrope walking. Tightwire is when the wire (or line) is tensioned between two points (Nik Walenda crossed Niagara Falls last month on a highwaire, essentially a tight wire suspended high above the ground), while slackline relies on the tension created by the person performing the act.
World-record holder Faith Dickey is one the best slackliners in the world, and on a deserted highway in Vrgorac, Croatia Faith demonstrated just why she is the best. In the video Faith ‘walks the line’ (with a short safety line) suspended between two speeding Volvo FH trucks. She has to complete the walk before the trucks reach two separate tunnels or… well there’s going to be some Wile E. Coyote-esque trouble. After nearly falling in the first few seconds, she manages to crawl back up
