I think anything smaller than a four-door sedan will be pretty much dead on arrival in the U.S. for most people. I don't see any reason that Americans would start preferring small cars because they're electric.
Currently, right now, yes, more infrastructure and ancillary or innovation need to exist to support such adoption.
The big leap here is I see those parts also coming together. Some things in China, others in Germany or Poughkeepsie (http://compositesmanufacturingmagazine.com/2021/01/high-tech...) ...the constituent pieces are coming together just like they are with the e-ink smartphone... There's a few of them (hisense a7, facenote f1, kingrow, ky-01l, light phone), they kinda suck, but it's clearly the future - there just needs to be another year or two of development
