This car was built assuming that power came from two cranks on the back of the car. The yellow for drive (bottom) and the blue for steering (top).
This is the "steertrain" that transfers the power from the blue knob to the steering. It goes from the blue knob down some axles to a set of 8 tooth gears. This changes the rotational direction so that when you rotate the blue knob, the car will turn right.

The drive knob just spins the differential that spins the wheels
