5/10:
1.Imagine you at unknown and unfamiliar map, you lost without any direction. So arrow dynamic props are basic of mapping which involving large area map.
2.After cp12 at bridge and take right jump into tunnel entrance, imagine this situation on bomb run attempt because minimum speed limit that time was above 100kmph+.
3.Also imagine the situation at tunnel exit and jump into cp13 or final cp (if yes), the car cant pass the cp because minimum speed limit above 100kmph+.
