Your calculations are interesting and indeed makes you wonder why EVs are selling in USA. I can tell you that the numbers here in Europe are dramatically different. And in particular Sweden with comparatively cheap electricity. 1 liter gas = 1.9 Euro means around $6.7/g 1kWh electricity is on average maybe $0.1 to $0.13 but fluctuates a lot between summer and winter. With solar panels you become self sufficient. FWIW the reason I stayed away from a Hybrid is the extra burden of maintenance and care. You get two different systems that can have troubles in their own way. In particular the gasoline part is much more sensitive and complex I'd say.
