Once you’ve managed to progress in the story a little bit, you will get a notice about being able to meet with Sharma Salsa in Banapur. Doing that will unlock two kinds of activities called Kyrati Films, which are races. The Survival ones are slightly different than the Racing ones, in that, instead of an overall timer, you have one that counts down and each checkpoint will add more time.
The other major difference is that you’ll need to switch vehicles while in the middle of the race, sometimes once and at other times twice. These side missions are repeatable, although you cannot repeat them to get more money. However, if you beat your best time, you will get the gold payout again.
There’s also a leaderboard that shows the top times by players worldwide, should you feel like competing against those a bit. There’s a total nine races, all unlocked by liberating outposts, and the only bonuses you get will be XP ones.
