Just some thoughts:

I've owned a first gen Leaf for about 6 years and it's my daily. I bought it for very cheap. My commute is about 25 miles total on surface streets and I've put about 40k miles on it. The usable range is probably 40 miles if you want to take care of this style battery, which I do because a new one is the value of the car.

It's been a good experience but I need to have a 2nd car or a rental if I want to leave town. It's worked for me, but there's no way anyone else I know would accept this.

IMO, the experience of "refilling" the car will need to be much quicker for wide adoption in the US, especially for those who are not able to charge at home. You'd also have to convince people that going electric is better for some reason, be it a feeling that you're saving the earth(which is debatable depending on all kinds of factors) or that the performance of some models is pretty awesome.
