Still not seeing the big picture? Consider this example:
You’re driving home at a low rate of speed. You don’t notice a car stopped at the intersection and boom, you rear end them. Your front bumper as suffered a medium sized dent, but since everything seems to be working properly, you exchange insurance information and move along. You fail to realize that disaster is brewing under the hood of your car.
During the crash, your bumper has a portion your radiator into the engine space and created a crack. Now your engine’s belt is now also rubbing against the pushed-in portion and it is leaking fluid. Within a few days, there is major damage: all because of a slight “fender bender”.
