Something I think we're missing the mark on with the EV transition is not taking the opportunity to make EV batteries more generic, which would make them cheaper to replace.

Imagine who's going to take the time and money to replace these batteries when these vehicles are 20 years old. Will there be classic EVs 20 years from now, or will they be disposable because nobody is making replacement batteries?

Yes, of course the economics of repairing classic cars is also an issue with traditional internal combustion vehicles, but isn't the goal of EVs to be greener in the first place? Disposable cars don't seem very green to me.
