I would think there would not be enough force behind our puny exaust pipes to do any good.

Also I'm confused about whether a large exaust pipe and free flowing muffler or a tiny exaust pipe with a stock one is better for fuel economy.
I have seen arguments for both.
The manufacturer of Aptera has a vent at the very tip of the end of the car from which interior air is exhausted. They placed it there, according to them, for the reason you mention above.
