Walker loved cars so much that he actually competed in a couple different racing programs. One of which was the Redline Time Attack where he drove one of his personal favorite cars, and mine as well, the BMW E92 M3. The Redline Time Attack was an event where the main objective was to pull the fastest single lap around a paved course. There was a very wide range of vehicles that could be seen there, most of which in stock form, and was perfect for honing in those driving skills. You never know when they might come in handy; say for example you make a movie about high-performance driving, or seven of them actually.
