The dashboard is derived from a wagon and refers to a partition installed in the front. It was first used to block dirt and gravel in a wagon, then it changed to separate the engine room and the cabin in automobiles. It is now commonly used as an interior component that houses various controllers required for driving, air conditioning, infotainment, and other devices. The dashboard is also called a crash pad, which literally implies absorbing the impact of a crash and protecting the occupants. Since it is the largest part of the interior of a car, it is considered a significant design element that determines the atmosphere.
