Unfortunately, battery requirements will likely never be met. The military's who have diesel electric submarines have been looking for battery upgrades since at least 1981 and those batteries have never been upgraded with other batteries. If the militaries haven't found a way, most likely their isn't one yet.Because democrats and lobbying. They should be able to stand on their own. Tesla and GM been doing that for a couple of years now.
And thats a choice, but its silly as hell to give someone $7500 for that choice.
I think they delayed the battery sourcing requirements for a year or two simply becuase virtually nobody can meet them immediately.
