Thanks for the thoughtful feedback. Air cooled is lower cost I think. And, obviously, a smaller battery pack is lower cost. ...There are trade offs.
The alternative for me was never going to be a $50K EV, but rather a $10K used ICE car. I'm happy with the choice overall and while we can technically afford any new car we wanted, spending more than that felt wasteful, so the tradeoffs you mention are entirely real forces on both Nissan and prospective Leaf buyers.
