Answer 1

The human body is basically an oven and we are constantly trying dump waste heat into the environment around us. Eventually, the air around our bodies gets locally saturated and we can’t dump more heat into it.

Now, when you hang your out the window and drive, you are constantly moving into fresh air you haven’t dumped any body heat into and this makes it feel cool.
