> First, the bottom has fallen out of the used market creating significant buyers remorse for early adopters.

The very high deprecation is often noted but the comparison is mostly in relation to sticker price, but the high discounts plus subsidies mean that the average discount for an EV was way higher than on ICE cars. Most of the high depreciation disappears once you take into account what the first buyer would have actually paid for the vehicle (often a five-digit discount), at least in my used car market. Some models seem to actually hold their value remarkably well, particularly those with no/few known issues and no real successors.
