Electron is not a particle but an incompressible fluid. 

Electrons flow in the wire must be like a rigid rod moves inside of a tube, therefore the whole rod and the whole electrons are moving simultaneously at any speed.

The electrostatic force/electricity/EMF/voltage in the wire is coexisting with the wire. The rod in the tube is coexisting with the tube.

Mechanical force and electricity are instantaneous.
