Yes, it's sort of the same idea as when a long freight train grinds to a stop at less than 1 mile per hour and then you hear the slack in all of the couplers going in, and that wave travels the length of the train at around 30 mph, even though the train is nearly motionless.
The secret to it seems to be that each electron does not have to travel very far until "bumping" its neighbor.
