This was no surprise to him. He told me a while ago that if Elon's claims were practical, my brother's employer would already have them in production.

Everyone is working toward those great improvements in battery capacities and production efficiency - they always end up being incremental.

I have seen various "internet" talks (such as TED talks) saying the same thing. We are decades away from battery technology that meets expectations. For that reason the future is fully electric in urban areas, plug in hybrids in suburban areas, and hybrids in rural areas.

Whether or not those "hybrids" trend towards hydrogen fuel cell hybrids over time or remain small ICEs will be interesting to watch.
