Paul,
300+ mile range isn't fictional. Or, maybe at least 250 miles.
Sure, if you rarely go more than, say, 100 miles in a day you can rent
something for the exceptions.
Using myself as an example, I need a vehicle that can go 200 miles RT
for excursions to the mountains. I go 20-25 times a year which justifies
owning a vehicle rather than renting. Plus, with a 15 hour day, I don't
want the overhead of another hour or two to rent something. Plus, rental
companies generally don't allow driving off paved roads, except for
short driveways.
I think there are many people who have stories, and in all sorts of
manners. I also agree, there are plenty of people who think they need it
but don't.

I would say that is only because people fictionally think they need a 300+ mile
range. My i-MiEV goes 40 miles now after 8 years 65 miles new and rarely will
it not go where I need to go. I have a Tesla now and it’s so much nicer I drive
it most of the time. But before COVID I drive the Mitsubishi everyday to work.
I love that car and while the range cuts it close sometimes I think With 100
mile range I would have Zero issues.

LiFePO4 only has about half the specific energy of metal oxide (like cobalt)
cells.
Because they are such low impedance (high specific power) you can reduce the
weight of the cooling system, (or perhaps eliminate it entirely) but that in
not nearly enough weight to make up the difference in an EV application.
LiFePO4 is best when you are more interested in high power, or cycle life, or
perhaps safety, than in maximum energy content per kg.
Cordless tools, starting, start-stop, hybrids, all are great applications.
EV's, not so much.

Obviously I'm not in any position to advise them, but I wonder if it might
be time for A123 to review their focus.
I don't know how dependent they are on the US market, but with the US
seemingly headed for both short and long term economic contraction, they
might do well to look toward western Europe and Southeast Asia for growth.
There the market for EVs and their batteries is ramping up quickly.
EVs there are (unfortunately IMO) getting larger, with more battery space.
Something of a range race is heating up, too.
If A123 can solve the energy density problem (I mean in terms of volume, not
mass), I suspect that they could also grab some of the warranty and spares
market.
For example, there are quite a few older 2012-2019 Renault Zoes running
round the EU. In most countries save Norway the majority have leased
batteries. Renault's contract says they'll service the batteries if they
fall below 75% capacity. If A123 could supply cells that would yield the
nominal original capacity (22kWh or 42kWh) and be the last service that that
battery needed, Renault's bean counters might take notice.
