The coanda effect is real. It can be displayed by placing a spoon into a vertical stream of water flowing downward, with the convex surface of the spoon facing down, as well. The spoon crates an example of coanda effect, displayed as adhesion. The water will briefly follow the curve of the spoon before continuing down. A spray with enough energy can actually temporarily reverse direction and travel up the curve of the spoon, against gravity.
How this would effect thrust on the car, I have no clue.
