I saw a post here recently that had a link to a Top Gear episode where JC raced Laguna Seca. JC's "teacher" had him practice the course on Gran Turismo between runs. Of course, it helps you learn the track. Other than that, I should think that only a real car can help you learn. I find it much more difficult to find the right line on a computer than on a real track.
