EVs are probably not going to depreciate as much in the future. The depreciation mostly happened because new electric cars have become cheaper.
As an example, let's say a 2 year old car is only worth 80% of an identical brand new car. The old car was bought for $50k at new, leading to a expected depreciated value of $40k. But since manufacturing has become more efficient a brand new car of the same model can be had for the same $40k. Nobody would be willing to buy the 2 year old car at the same price. You'd probably have to charge only $32k [0]. But then it looks to you as if it has depreciated 36%.
The question is how much new electric cars will fall in price in the future. And if they continue to fall, at some point the dollar value of the depreciation will be too small to care about.[1]
0: $32k = 0.8 * $40k
1: E.g. if a new car is $10k, $3600 in depreciation over two years is annoying, but not a big deal.
