Once I have accepted the "Recover ID Drive" quest, and then travel to the Ark, the Authority have blocked off the road near the bottom-level entrance to the Wasted Garage. This makes it impossible to drive the ATV close to the field goal near the Ark. Is it possible to score a field goal here later in the game? i.e. will the Authority road block be removed later in the game? Or is there some way to jump over the road barrier in order to get into the area between the Wasted Garage and the Ark?
