I'm thinking they might sell/license the rights (not sure if that's the right phrasing) to these charging stations along with the maintenance/repair costs to a private company. If they spend $100M to decommission them, I will be very surprised.
Rental car companies ended up selling teslas for under $25K back when that was unusually low for an EV.
These days, a decent used EV costs less than that, so I imagine the government will have to dump whatever model they have 25K of for $20k or less. That’s probably still more than 25% msrp, but not by much.
This does not seem likely as even by adding this many cars to the market, there’s no way they would sell at 25% of value unless there’s shenanigans.
