Side-gliding is when you turn your torso sideways to avoid bumping others. It’s very useful on walkways with limited width and anywhere there’s a crowd. I often side-glide through grocery store isles, and the technique is virtually necessary when walking on a crowded subway car or platform.
A great cinematic example of this action is demonstrated in the film Remo Williams: The Adventure Begins, or (for younger readers) The Matrix– where the hero employs a side-glide technique in order to dodge bullets (though we do not recommend extending your arms like Neo).
Dodging other walkers is certainly easier than dodging bullets, and we suspect many of you have been side-gliding through throngs for years. Mastery of the technique is not only a polite exercise of human mobility- but at most can reduce chances of becoming involved in a street fight.
