There's a big generational tech advantage, so we're seeing big depreciation on older EVS. I expect that trend to continue for at least a few more years. The 2017 Chevy Bolt for example will end up probably costing less than $10k here in two more years. That's pretty cheap.

You also have to keep in mind that the economies of scale for EVS are just ramping up. They're more expensive now brand new but it won't be long at all before they're priced competitively against gas cars at the dealer.

Also, a carbon tax will happen sooner or later. That will push people from all income levels towards electric vehicles.

Yes, once EVs have matured they will keep their value after adjusting for subsidies (there are lots of stupid articles that don't understand why a used EV with 0 miles goes for 5k less than a new one). However, this should make financing a car more predictable.

It's better to own something that costs X amount per month than to get a steal and have unbudgeted surprise expenses if you are poor. Exploitation happens when someone is unable to make an informed decision because of information asymmetry.
