The actual mean drift velocity for electrons at any reasonable curent
is quite low because there are so many of them in the conductor.
However, the electric wave driving them propagates at he speed of
light appropriate for the medium.


The electrons move hardly at all at RF/AC frequencies.
On the average, they tend to oscillate mostly in place.
What travels at the speed of light are the photons
emitted by the oscillating electrons. The electrons
form the equivalent of a "bucket brigade" for the
photonic wave energy.
