Double Mirror / Rear View Mirror

This is an electronic-spinning side mirror which can solve the problem of vague view caused by rainy day.
When the rain affects the vision of side mirror, we just spin the side mirror to the other side which is dry and then you can have anall-new mirror withnew clear vision.
We use the flow separation discipline of fluid dynamics tolead the wind into the chink of the side mirror,and let the wind pressure bringthe water out to dry the span wet mirror inside.
