I guarantee even a professional left-pedal installer uses right-handed threads exponentially more than left-hand threads. They are uncommon. Off the top of my head, I really can't think of any place I've used them OTHER than on a bike, and how often do you muck with your left pedal and/or lockring?
I suppose it was the "ever... in your life" part I disputed. Not the idea that left hand threads are rare and counter-intuitive. I change pedals all the time, but then I'm kinda twisted the wrong way myself. In fact I might just be the left hand thread of humanity.
