Yeah if you wanted the driver in the center of the car you would just move the model in your scene to the center as well. Like in my image above you can see the driver is to the left side of the center 0,0 coordinates in the scene so the driver will be on the left of the car. It lines up with the size of my car model so they are in the seat. I have the driver in a seperate emtpy scene so its easier to manage.
