"In a step-by-step process, examine the purpose and various uses for every scriptable property of the vehicle systems. Vehicle scripts present a particular problem due to the complex, hidden interactions between variables. With Source Vehicle Scripting, you'll learn not only what those interactions are, but you'll also go through examples of how to fine tune them to get the results you are looking for. From a car that falls up to a drag racing sports car, you'll run the gamut of possible changes and learn from experience the limits of scripting."
