The other day, I was on my way to pick up groceries—not exactly running late, but not leisurely either—when I drove over a couple of black rubber cables stretched across the road. You’ve probably seen them too, just lying there across both lanes, like someone forgot to clean up after finishing some construction work. They make that soft “thunk-thunk” sound under your tires and then you move on without giving them another thought. No flashing lights, no warning signs—just those quiet, mysterious tubes.
