Yes, Demand is probably the wrong word.EV "Demand" is not a good measure - the "Demand" is that far ahead of "manufacturing capability" that it's not funny
There is a void between what the demand is for, and what is actually available
I suspect that anyone who really "wants" an EV , could go out today and buy one, possibly even drive one away. Im sure Nissan (Leaf), GM (Bolt), Ford, BMW (i3, 530e, etc), Renault, VW, MB, Tesla, etc etc would be happy to cater to you (Sure Tesla will make you wait most likely)....depending on where you live.
But the point is, EVs are readily available, just maybe not in the form or cost bracket, that the mass market demand wants !
There is a "Market" for practical, affordable, EVs, ....but that EV doesnt seem to exist yet.
