Let us try to explain how this brain-melting idea works: you must race & manage multiple tracks at the same time. You are able to switch between the different tracks of a race any time you like. When you switch away from a track, a computer racer takes over driving on that track for you.
Unfortunately, the computer racers aren't what you’d call competent. They are what you'd call incompetent. But in a clever way. In other words, to place well in every track you're racing you’re going to have to hop from track-to-track on a regular basis to account for the subversively cretinous computer cars.
