    The whole poll does not move as end entire unit instantaneously. You send a sort of shock-wave through the poll, when you push it from your end. That shockwave has a travel time that’s much slower than light. I suspect that the speed of that shockwave probably proportional to the speed of sound in the material that the poll is made of.
