At hero selection stand, you can choose ADriver that fits your driving style best; it will represent you all over races. However, you may have few drivers to race for you, here you can select them and upgrade their abilities. Each of them has a unique set of skills that will help you in most insane off-road racings ever.
You have the ability to exit the car (RB) with you chosen ADriver and to loot AirDrops and supplies, that are dropped by jet fighters around the track.
While ADriver is out of the car, time is slow to some extent to the other cars, so you can still get back and be close to the car to be able to enter (RB button again) and get back to compete. ADriver is risky features, however, if you’re skilled it can bring you many loots, needed XP, AD$ to obtain more features, customizations, cars and other assets.
Also, your car is equipped with few ADrones, for evading harsh situations or to circumvent above other cars, when they obstruct your way. Since you need to continue to compete, and there is no time to lose, and you can simply get into drone mode (LB button, if you still have it) and continue toward next checkpoint and respawn the car bellow safe position (LB again). However, both the number of ADrivers out of the car and ADrones are limited, also time outside is ticking, so you need to utilize skills, find, loot and get back close to the car to be able to enter before time expires, or your car will be respawned to the previous checkpoint and you will stay out of the loot.
