So it is to be assumed that a person is travelling unless there is evidence to the contrary.
Correct. If the state thinks that it has evidence to the contrary and can prove its case (that you are not travelling) they can go ahead and prosecute. At least 3 DAs have stated their intent to do so.
About the only possible evidence to the contrary would be that the person is out of the vehicle concerned. Every english dictionary defines travelling...
Before the passage of this law, TX law already said that if you were travelling, you couldn't be convicted. If it were as simple as you imply, there would have been no need for the legislature to try to make the law less restrictive.
Here is a comment from an explanatory letter about the law. The letter is written by Terry Keel, one of the TX legislators who penned the law.
The legislature has likewise never defined “traveling” because a definition invariably has the unintended effect of unfairly limiting the term to a narrow set of circumstances.

In enacting HB 823, the 79th legislature, like all previous legislatures, declined to define traveling as a narrow set of particular circumstances.

The presumption applies unless the prosecution proves beyond a reasonable doubt that the facts giving rise to the presumption do not exist. If the state fails to prove beyond a reasonable doubt that the facts giving rise to the presumption do not exist, the jury must find that the presumed fact exists.
The new law does NOT define travelling. The new law does NOT change the legality of carrying a handgun in the car without a CHL. It ONLY moves the burden of proof from the citizen to the state. Practically speaking, it will make it MUCH more difficult to prosecute these cases, but that does NOT mean that you're home free as pointed out below.
Can you still be prosecuted for having a handgun in the car in TX without a CHL? Clearly Mr. Keel thinks so--so does NRA/ILA legal counsel.
HB 823 Bill Analysis Provided by the staff at NRA-ILA
Texas H.B. 823 prevents the police from routinely arresting a law-abiding person who is transporting a concealed pistol in his motor vehicle. This is accomplished by clothing a law-abiding person with the presumption of being a traveler. The traveler presumption may be rebutted by the state by presenting proof beyond a reasonable doubt.
Before the law you could carry a handgun in the car if you were travelling.
After the law you can carry a handgun in the car if you are travelling.
Before the law you had to prove that you were travelling or you would be convicted.
After the law the STATE has to presume that you were travelling and therefore must PROVE that you were not if they hope to convict.
