To me the key design features are aerodynamic efficiency, weight-saving materials, passive charging, and surface cooling system. Anything else I don't care. Get a skateboard from LG Chem. They designed a nice system for the Chevy Bolt. Either the fundamental design principles are correct and will work, or they won't. I would like to see the design materialized as a production vehicle. Maybe the founders and us early adopters are deluded. Better to go out in a blaze of glory than slowly sink into obscurity!
