I think he means like an steep incline or a driveway. Have you ever scrapped the bottom of your car trying to pull out of a parking lot, neighborhood, or driveway? Because I do it atleast twice a week, and I'm pretty careful about. I'll even take a picture of where I live if you want.
We have a lot of New Jersey students that come to WVU with their modified cars and body kits only to completely destroy them in a few weeks, weather it'd be bottoming out, curbing their wheels, trying to parallel park, or whatever. It only takes one time to destroy a lip or something.
