I can get the booster but can’t make the car crash!!
When I get to the mine road I get all the weapons, booster and googles; pick up the ramp, and when I go to the guys in the car they just chase me forever and don’t crash the car!! It like I never got the booster at all! I did the same thing like three times and can’t get trough...
Unlock the wheel nuts of the trailer and then kick the trailer. It should fall and empty all its content on the road. When you get chased afterwards the car will crash.
