If these things start rolling off in any volume, that will drive the price higher still. It also doesn’t sound like recovering most of the silver in totaled or discarded cars will be practical.
Still, if we are talking $40,000 cars, and the tech is that much better, it still might be worth it for those who choose or are mandated to purchase electric.
I doubt that buying batteries that cost $2000 over and above the price of normal EV batteries makes any economic sense. They’re not that much better. That would add 5% to the cost of a car. Keep in mind that the cost accountants who seem to run every auto company these days get very enthused if they can save five dollars per car, so as to make their vehicle more profitable and more competitive with those of other manufacturers. An extra $2000 seems to be completely off the table.
