But, and I have posted this before, my opinion is that ti has no effect on someone in a car.
§46.035 makes it illegal to openly carry under the authority of a CHL, but doesn't apply in your home, where you don't need a CHL to carry. §30.06 makes it trespassing to carry under the authority of a CHL, but doesn't apply in your car, where you don't need a CHL to carry. It might be uncommon in practice, but it seems simple and clear-cut as well.
