Sorry, that myth is refuted by this video: https://www.youtube.com/watch?v=XFdkLFvqbZY

Worth noting is the surface area around the bottom and sides of the engine compartment are far greater than the combined area of the radiator opening and hood scoop. It is therefore easier for air to exit under the car and through the wheel wells and side vents than it is for it to exit through the hood scoop - though that may be different when idling in traffic.
