i would actually like to know if such a low gear ratio exist too.
worm gearing does provide such ratios, but because spinning is only allowed from one side to the other (e.g. motor to the wheels but not back) your motor will always need to be spinning faster than your wheels. which is a problem. i dont think it's very practical to use that in a vehicle.
i think the common solution to this is a dual step down gear, 5:1 to another 5:1. that's how it's done in normal transmissions plus differentials too anyway.
