The link you posted is not the law of Texas. It is a forum based on the "common law" argument that state/federal laws do not apply to anyone.
Since the car is not yours you have no grounds to prevent the officers from searching the car. Since you claim the bag did not belong to you, you cannot assert any right to prevent the officers from looking in the bag.
You were driving a car that didn't belong to you and you had no identification on you. You essentially had no rights to prevent a search.
