When air flows over an airfoil, the air flows at the top flow faster than the bottom and hence creates a net pressure difference, and thus an upward force is applied on the wing. Thus the airplane lift from the ground and keep flying in the air.
Now, imagine the side view of a car. Car shape, in my opinion, looks very much like an inefficient airfoil. It is flat at the bottom and has overall "round" shape at the upper. So, why not when the car is moving on the ground and hence the air flows through it, the same effect on airfoil happens on the car, and thus give rise to a lifting force (the force might not sufficient to lift it off the ground)?
Is it because the car is too close to a solid ground but airplane's wing is in the middle of sky so the "ground effect" makes the car doesn't experience what the airfoil experiences?
Looking forward to any inspiring thought and explanation.
