The extra gears were just from playing with the parts.
It's a shame the lego motors run so slow. With the worm drive you lose a lot of speed, but outside of a transverse mount arrangement for the motor, I don't see a way around the worm arrangement. And the modern lego motors are way too long for that, and the older motors are really low power.
