So the reality is that range increases are due to battery capacity, which is not really "efficiency".

So the way I’m reading that is either things are near the peak of their efficiency, or that companies aren’t focusing on that.

But regardless the case. The biggest increase in range is due to an increase in battery sizes, but it’s also at the expense of weight.
