I would argue for a more holistic approach. Sure, optimize current resource consumption and even bring technically inferior but more practical batteries to market, but also do not assume the electric vehicle end-state = swap electric for internal combustion. For instance, would we have a possible resource crunch if US car ownership went from >1 car / person to 0.1 car / person or lower? That could happen in a few years now, with Uber / Lyft running on fossil fuels. What if self-driving, electric vehicles come to market not as personal transport, but instead as transportation-as-a-service?
