What am I missing here?
It is true - aero drag has a huge effect on the range. At just 30MPH, the aero drag is ~50% of the load on the motor. So, even a few changes that reduce the turbulence caused by moving the car through the air will show up on range.
And you are right that lowering the drag will make the car a better value without increasing the cost. Nissan did some things to lower the drag, but htye certainly could do a lot more.
Nissan could have thermally activated shutters on the cooling air intake. Then you would get lower drag until / unless cooling is needed. In the winter the heat could be harvested by the heat pump, before opening the shutter.
