Honest answer involves deep breaths (at least as one first adopts the method), chuckling at one’s favorite podcast, and recreating the buffer.
On certain roads, monkey see monkey do and eventually folks behind you kinda copy you and there’s a chance fewer and fewer folks will be cutting you off. Notice this most on the longest trips. Perhaps they’re not copying you, btw, rather the most aggressive drivers continually pass you until a small cohort of Big Spacers remain behind you. If some of these Space-Not-Racers are in front and around you too, aggressive drivers passing are passing without cutting you off as much - they have enough space to jam themselves into the bumper of the car in front of you.
Kinda funny going around a curve and seeing a hundred cars bumper to bumper ahead, then checking mirrors to see safe following distances :) (oh yeah this style is safer too not just more efficient!)
Can require some SERIOUS brain hacking. How mad would we be if someone cut in front of us at the grocery store? We’d go butts2nuts in a blink. Gotta just, like, flowww mannnn
