You’re right and he’s an idiot
A knot will weaken or be a weak spot but not a twist
There are also bad habits that have been ingrained into the minds of many drivers and are passed on to others. Take for example the widely held belief that a strap that’s twisted once atop the cargo it’s meant to secure experiences less vibration and therefore provides greater securement.
“There’s no truth to that at all,” says Allan Boomer, sales team leader for Kinedyne in Canada. “Straps are tested for tensile strength using a straight pull. When you twist a strap it’s not a straight pull anymore, so you’ve compromised the overall integrity of the strap. A lot of guys do that because of the vibration, but if they add one more click to the winch to tighten the strap a little more, the vibration goes away.”
