Good points, Ben.
It's interesting to note how gas gauges are set up, psychologically.
Here's one explanation:

Compared to that, I appreciate the numeric charge percentage display on
LEAF V1.5.

That works for me, and it pretty much sums up what LEAF V1.5
(2013-2015) displays right now.
Good to know that it's a feature of one of the first-tier electric
vehicles on the market. Gives one hope that it'll be a standard long
into the future -- and, hopefully, one that gets refined with future
generations.
After all, it's not uncommon to have gas gauges on ICE vehicles that
behave less than ideally linearly due to tank shape or voltage
regulation or whatever, but I don't know that it's been a big
priority for manufacturers to improve gas gauges over the years.
But an EV should have far more than enough computational oomph to do
whatever is needed to properly refine a measurement of remaining kWh.
If experience shows that the estimate is too optimistic over the
bottom quarter of the display range, it's not _that_ hard to
initially add a fudge factor to the software...and, eventually, some
smart analytics to truly nail it.
