That is by design Winston. The rear fog is located on the driver's side of the car only, to let traffic approaching from the rear know which side to pass on. In the US, if equiped with rear fogs, they will be on the left side. In countries which have RHD models, the rear fogs will be on the right side.
Hope this helps.
