So when you drive into the trailer with your tractor you only have to fix the RV, not the back wall of the barn that the RV rolls through. Also, a properly built slab to park vehicles on has a 1/4" per foot slope to drain water that falls off after driving in the rain so many slabs aren't totally flat.
Why do you wear a seatbelt? Why do you have smoke detectors? We do all kinds of things daily that turn out to be totally unnecessary.
