At the velocity electrons travel in metal (nearly 186,000 miles/sec or
almost a trillion (10^9) feet/sec), that length difference wouldn't matter.

Actually, electrons travel very slowly in metal -- a fraction of an inch per
second, IIRC.

As individual electrons, yes, but they force their neighbors to move and the
net effect is a flow at a decent fraction of the velocity of light.
