The best analogy I've heard for explaining Texas to non-Americans is that Americans view Texans the same way the rest of the world views Americans.
Reversing some of the substrings in that string would also result in a very good analogy.
Texans view Americans the same way Americans view the rest of the world - derisively, but it is those viewers who should be derided, and often are, by the groups that they deride.
Somehow I forgot to mention truck nuts. Car culture is something else entirely in Texas.
