Why, at a low speed of the ordered movement of electrons in a metal conductor, devices included in the same circuit

Why, at a low speed of the ordered movement of electrons in a metal conductor, devices included in the same circuit and located at large distances from each other begin to operate simultaneously?

The electric field in a conductor propagates at the speed of light. Because this speed is very high, then the electric field appears in the entire conductor almost instantly, setting in motion the free electrons of the conductor.
