It has generated some controversy, but one of the Ars Technica car editors has been saying for a bit now that every car is starting to be a "computer on wheels" and EVs are especially a "computer on wheels". With an EV even things like "driving feel" are less the domain of mechanical engineering and more the domain of firmware-described software curves. Software stability and update processes matter a whole lot more for EVs (especially if that sort of firmware that defines acceleration modes/curves or in this case battery management is itself updatable). The software starts to matter a great deal more than just how it mechanically drives in a test drive.
