Only diference with a NASCAR spoiler is its for downforce. The trunk spoiler gets adjusted for th balance between speed (laid back) and cornering downforce (stood up).
notice on the Mekur and the white car the spoiler is level not vertical.
pickups are adding a "step" on the top of the tailgate for the same reason.
