Hit the rises at as big of an angle as possible.

just drive the damn thing!

depends on how low ur car is. if ur car is low or already scraping, then go up it slowly. if that doesnt work, its going to scrap. either remove the lowest part of ur car, guessing its the skirt, or decrease the incline. u dont have many choices if u cant go up it slowly without scraping.

look where you are going
