The first and most obvious way the GTR developers have done this is through the driving school, an expansive tutorial that has seemingly been designed to take you from the ground up--from your first moments in the car to competing tightly with the game's demanding artificially intelligent drivers (or with up to 27 other players via the game's excellent online multiplayer racing). Categories covered in driving school include the basics, such as acceleration and braking, up through cornering and overtaking, and finally, into section-by-section breakdowns of many of the tracks featured in the game. Each category includes a text breakdown that covers the theory behind each racing concept, as well as the specific goal you need to accomplish in order to pass that particular challenge. You can also practice the challenge before an "official" attempt against the ghost car or watch the ghost car's lap to view proper braking or turn-in points, which is essential for some of the trickier challenges. By beating challenges, you unlock a host of restricted-class championships that are graded in difficulty levels; some of the first championships you open are quite easy and serve as an excellent introduction to the kind of intense on-track action that forms the heart of the game. Those new to the series are well served by simply going through the basic tutorials in driving school, unlocking a few championships and competing in a few of these early series. In all, if you go so far as to compete in all 142 challenges found in GTR 2, you'll be well on your way to mastering the fundamentals of driving quickly and have a good idea of how the many tracks found in the game operate.
Once you're done with the tutorials and have built up a heap of early-game confidence, you'll find a number of game modes and options in GTR 2 just waiting to beat you down and bring you back to earth.
