You have to distinguish between "Electron Travel" and "Signal Propagation". Take a 10 ft plastic pipe of the same diameter as ping-pong balls. Fill this pipe from start to end sequentially and fully with ping-pong balls. Now stick your finger in one end. While you only moved the ping-pong balls a few inches, almost immediately a ping-pong ball will come out the other end... The "signal" "traveled" at a much faster speed than the actual ping-pongs.
