Vaughn Gittin, Jr. is a professional drifting champion. The Ford Mustang is a muscle car that is built in Flat Rock, Michigan.
This is what happens when you put the two together.
Just like Ken "From The" Block, Gittin is sponsored by Monster Energy. That means his contract probably stipulates that he has to participate in at least one gymkhana-esque event.
For his driftravaganza, Gittin took a 2013 Mustang off the assembly line and proceeded to drift it around other Mustangs at the Flat Rock plant as part of a "comprehensive track test." It indeed is comprehensive, and he only hits a couple other Mustangs along the way.
