I think there will be an inflection point in the not too distant future where EVs become cheaper than ICE vehicles, and that will cause an abrupt change in consumer behavior. Major changes seem impossible until they happen, and then afterwards people say "what took us so long?" if they think about it at all.

Batteries are the main problem right now; everything else in an EV is pretty simple and cheap. Apparently there are some major patents on lithium iron phosphate batteries that are about to expire; hopefully that means we'll have a lot more production outside of China. LFP batteries don't require cobalt or nickel, so they can be made in higher volume with fewer resource bottlenecks.
