It is to generate a vortex of air so a wormhole can be formed just behind the car. Once the wormhole has been generated, the forces of gravity will push the car down and forward thus adding to overall clownforce and adding an additional 15% BHP and a further ~10% wHP if the wormhole is just 1micron away from the sonic hair.
This phenomenan is how sonic is able to run upside down when he achieves teminal velocity and goes into spinning mode. Scientists have been able to copy sonic's speed while eliminating the need to spin before achieving terminal velocity (via 10% WHP increase in power and additional clownforce) by placing the row of sonic hair in parallel to the wormhole instead if in line to the wormhole. By doing this, scientists have been able to average out the forces produced from the wormhole thru-out the surface of the vehicle it is placed on.
Scientists have cautioned though that there is a chance that the sonic hair if improperly installed with cheap double sided tape will come off at high speeds. When this happens, the wormhole becomes very unstable and instead of pushing the vehicle forward and down, it instead becomes a pathway to Thor's homeland. This has only been recorded once during testing and this was the root cause of the huge tsunami which happened thruout the Indian oceanfront which caused widespread destruction. Thor was shitting at that time and did not enjoy having a wormhole suddenly open near his anus sucking on his excrement hence sent his hammer thru the wormhole which was the root cause of the creation of the mega tsunami. Stories of the tsunami being caused by a giant undersea earthquake is a hoax. Everyone knows that earthquakes are caused by surbo's that are improperly installed which disrupts the strings of universe. Users can rest assured that all currently sold sonic hairs will not so easily fall off at high speeds as manufacturers have signed an international accord that all manufactured sonic hairs AKA vortex generators will be affixed with 3M double sided tapes.
