As for exiting the hot air back to the dead spot, good idea I think.

This might be only true at low speeds (20-30 mph).
At higher speeds (55 mph) enough air will flow from the ducts.
Although most driving might be made at really low speeds during rush hour, so neither front or back radiator placement will provide enough flow by themselves, you need a fan.

Thanks for providing the technical name Meredith effect. Will post more on this soon.

It works the same as turbines and rockets.
Heated air has more pressure thus producing thrust.
