Don’t get me wrong - I’m glad consumer EVs are a thing for multiple reasons, but I’m frustrated that more publicly-funded research wasn’t done on heavy-duty systems. The obvious entry point in the American context (since we hardly publicly fund anything except our military) would have been to focus on battery and series-hybrid implementations for heavy transport and armored vehicles, which could likely be adapted fairly easily to civilian markets.
But I think what stopped it is that it would have required a ton of infrastructure investment, and that’s one of the things we don’t care about funding most of the time. That, and all the ICE manufacturers and oil companies probably lobbied their asses off to kill anything like that.
