A Quick Race is just that: a single race against one or more computer opponents. You can set up a race in two ways.
a) Quick Play
The computer randomly selects a track, number of opponents and a car for you to drive. You can accept what you are given, or press [1] to randomly select a new track and car.
b) Custom Race
You select a course, the number of opponents, the amount of traffic, the probability cops will show up, the difficulty level and whether or not you want "Catch Up" AI turned on. (Catch Up is also known as "rubber band" AI because the computer cars are never allowed to get too far behind nor too far ahead in the race.) You also choose your car from among any of the stock or bonus vehicles that you have unlocked, or any of the cars you've built up in Career mode, or any custom cars you've put together with the My Cars feature.
