At a guess I'd say that the spec wasn't quite competitive enough at the price it was pitched.
Consider that the C64 was also launched in 1982 for a much cheaper price and was available in non-NTSC regions too, so would have had a bigger software library available to it.
Many people can put up with less convenience with peripherals if you're paying an order of magnitude less up front.
Even the software on cassette and 5.25" disk would have been so much cheaper to distribute than the newly launched 3.5" disks (which were much better).
Digital Research had GSX, which provided a rich set of graphics primitives. Sony would need to offer a device driver or, alternatively, make the console/terminal emulate a graphics terminal such as the DEC VT-240 (and GSX would use a Tek4014 or ReGIS backend).
A lot of CP/M machines had graphics-capable built-in displays. Unfortunately, publishing software in machine-native media was a real chore back then, a bit like in the 1990's, where we had a "Unix version of NetScape" which was actually 27 slightly different versions for 27 different operating systems and binary architectures.
The video covers how CP/Ms big problem was that the disk formats weren't the same between machines, doubly true for this Sony which used new 3.5" disks. So all the existing CP/M software had to be specifically re-released for this machine, which caused a chicken and egg problem (who is going to release software for a machine nobody is buying because there is no software for it)
The MS-DOS world solved the problem by everyone just cloning the IBM hardware down to the disk format.
Kind of, because while MS-DOS was compatible between PCs, CP/M depended pretty much on what 8 bit machine you had, and like UNIX required compilation from source for proper compatibility.
FTL Modula-2 for example, had several low level portability modules depending on which CP/M machine you were actually using.
Both are irrelevant for your sub-100-mile daily commute, and the additional initial charge for a twice-a-year road trip is a rounding error.
The additional range is nice for home charging when you regularly do 500-mile-plus daily round trips, but that's way beyond regular commute ranges, and someone like an on-location service technician will have the company pay for it anyways.
I won't say that nobody does it, but we're definitely talking about edge cases here.
Either way I think the benefit for me would be after the vehicle is well-worn and only has 10 or 20% of its original range remaining.
If it was so much more efficient than average to begin with that could make the difference whether it was still viable for daily use including short commutes for a number of additional years when almost all other vehicle choices would require a new battery at that point.
Batteries are a bit like capacitors, and I think people are aware how some of the shoddiest capacitors were placed on motherboards for a while there before people figured out how substandard their lifetime was after it caused so many premature failures.
However the engineers who used about twice as much capacitance as the minimum to start with, whether it was intentional or not, were not struck nearly as bad.
Why can't an electric car be fun to drive? I have an old car I'm not planning on changing but electric cars I've driven just seem quieter, smoother and just better than ICE vehicles.
They whole point of that article is that it's a weird, curious thing from the past that doesn't exist any more.
