Additionally, use non-combustible external materials and incorporate an exterior fire suppression system that draws from your own underground water source. You'll need to have your own power source and battery backup to run these pumps. You're looking at $100k for a modest residential structure. Insurance does not give you break for having this in a residential, outside of an insurance rating with -W modifier for the water source.
Vehicle mileage is taxed at the pump and at the charging station. The material is taxed at sale. Charging an excess tax is just. . . In excess.
