While I really love seeing these new types of innovative e-vehicles, one aspect that remains underreported is that  any kind of enclosed vehicle without adequate passenger cooling will not be feasible in many, many Southern locations.  I live in Austin Texas and just spent 5 weeks in San Francisco, California, which was like being in a windy refrigerator in comparison to Texas.  It is very hot and very humid in Texas and the heat is stifling for nearly 6 months each year.  This kind of enclosed passenger compartment might not even be survivable in Texas, so this is a major constraint on the potential market for such vehicles.
