There are parallels with what has happened with Kit Cars since The Fuel Crisis, at least. You could build one today with plans from a Popular Mechanics if inclined. What we have today with tech advancents, build-out of infrastructure and acceptance of the technology seems to have little impact on that "kit" approach. I think a better analogy might be the Pre-War Automobile Coach-builder. The body was made by a different company than the drive train. Economies of scale and the demand for cars changed that. A new class of Automobile could arise if a company could farm styling out to a famous house; Ghia for example, build a body from that design, and have an opportunity to provide interior fitment and design to the degree of Bentley and Rolls Royce, or down-spectrum toward Kia and Suzuki. In any case, we're likely to see eddies like Water-cooled, UV-reactive power converters and fiberglass monstrosities as seen at a 1970's Autorama.
