This page of the Saints Row guide describes side activities from the Side Hustles category available in the East Providencia district. Each of them has its own goals that must be met to receive the reward.
Rewards for completing the Riding Shotgun side activity:
- 1,200 XP,
- new weapon modifications.
While completing the task, you have to get rid of all opponents while sitting on the roof of a speeding car. Try to keep shooting at the enemies so that they do not get too close to the car. After eliminating the enemies, the mission will end and you will receive the rewards.
