I started telling people during the gas crisis of the 70’s that they way to go was a small ICE powerplant used as a generator not a motivator. And that it’s only purpose should be to run when necessary to charge the batteries. With that setup you could drive on electricity forever as long as you kept some gas in the tank to produce said electricity. Nobody listened. They are listening now. A couple of auto makers Scout and Ford are looking to offer that setup in the trucks and SUVs.
And that's why some enterprising individual (Republican) should start producing the EV "travel/charging trailer".
A small trunk-height, aerodynamic unit with an appropriate sized generator and some extra room for fuel and luggage or stuff.
Those unsold EVs should be going dirt cheap soon, and if the charging trailer is reasonable, it should be a good deal for a certain market. You probably could sell it (or the patent) to the dealerships to be offered as an accessory.
