Rebel Racing Multiplayer Events are A-Synchronous, meaning that when racing against opponents you are racing against their Ghosts, which is a recording of them doing the race.

While you are playing, other people may come up against your Ghost, which is your latest time set on a particular track. If you crash during a race, that time won't be considered as your latest time set. Your opponents are chosen based on your best time in the particular race within the event.

These races also affect your score, so you can gain and lose points while offline in the same way as if you were racing online.
