Do you have a link (or know the text) of the new law? I heard it was changing on September 1st so that your car is considered your home.

Texas gun travel law changes.
Section 46.15, Penal Code, is amended by adding Subsection (i) to read as follows:(i) For purposes of Subsection (b)(3), a person is presumed to be traveling if the person is:(1) in a private motor vehicle;(2) not otherwise engaged in criminal activity, other than a Class C misdemeanor that is a violation of a law or ordinance regulating traffic;(3) not otherwise prohibited by law from possessing a firearm;(4) not a member of a criminal street gang, as defined by Section 71.01; and(5) not carrying a handgun in plain view.
