I am curious as to if anyone has tried practicing by playing driving / racing video games. Granted, it's not truly "practicing" because, well, you're not driving a real 3,000lb vehicle and the physics aren't going to be "real world," but many of the decision making processes are exactly the same; speeding up vs slowing down, left vs right, quick decision making to avoid an accident, etc.
Even the more exaggerated games, like what I played when I was younger, like Extreme G, San Francisco Rush 2049, and later games like Dirt 2/3, Burnout Paradise, Flatout (not 3, which is terrible, I hear) do at least familiarize you with some of the more extreme situations so that you might be able to recognize them more quickly in real life where they will typically be far more subtle.
It's not a 1:1 skill set by any means, and I'm not saying you'll be able to drive a car because you can play a video game, but they both operate the same kinds of thought patterns in the brain and can help to acclimate you to the "sensation" of driving and perhaps take some of the shock value away from the (usually) mundane real world experience (bonus if you can actually use a desk-mount wheel / shifter setup, but a gamepad works, too).
