You need to be skeptical about environmental issues. Whether or not EVs are less green to manufacture than RICE vehicles requires estimating the emissions related to manufacturing requires assumptions, such as the fuel mix of the electric system serving the manyfacturer. There are sthose who want to discredit EVs (and all environmental impovemets) for their own reasons, and some of the studies they commission include some sketchy assumptions. The real answer is EVs are part of transition to a low emission green energy economy, and manufacturing processes that are dirty today will be cleaned up in the future. That's the plan, whether it works or not is a different issue.
That's what my Grampa said until Model Ts replaced Packards. The way to make the transition to EVs happen is to make everyone want one. You do that by making cars everyone wants, not by making electric Yugos. The cars everyone wants are always expensive.
That's mostly an infrastructure problem. It will go away when EVs reach a critical mass. Some day you'll give up your RICE vehicle because it's too hard to find somewhere to gas up.
