Car spoiler for a better drive
A car moves through atmospheric air on the road. As the car moves the air exerts pressure on it. One would presume that the pressure would be in the direction opposite to the one in which the car is moving. No doubt, it is correct to a large extent, but the air also exerts pressure in another direction. A fast moving car would experience an upwards thrust. If the car happens to be particularly light, its grip on the road will be lessened due to the upwards thrust. The car spoiler is of use in countering the upwards thrust.
