Except this isn't subjective. It's about FACTS, and it's totally objective. There's no possible way you can make a case for Teslas being better for the environment vs an average gas powered car.
In your "calculation" you generously dismiss the energy needed to find, source, produce and transport the gasoline, whereas with electric engines, you calculate the whole process from adam and eve
We do have 100 square meters of photovoltaik on our roof and produce more electricity than we use with my several music systems, the homecinema, the huge house and the hybrid Volvo of my wife. The overproduction is sent into the electricity grid.
I do have a Corvette C7 but I would love to have a Tesla S.
My C7 is just too new to change to a Model S.
I testdrove the Model S and even compared to my beloved C7, the Model S (90?) was at least as much fun to drive as my C7
My wife has a Volvo V70 hybrid that can make about 50 kilometers with pure electricity and it's the perfect car for her.
She drives purely with electricity 80% of the daily commuting to work and shopping and when she goes hoerseriding further away and pulling the horse trailer, she uses the "normal" engine in the Volvo.
We like the Volvo a lot and it's wonderful to drive because with that concept, you can have it all:
Drive purely electrically within the daily commuting range
Have a powerful all wheel driven car when needed to pull a trailer (manually switching to all wheel drive)
Have a very comfortable, quiet travel car with quite some overtaking power at the push of a button "Power" to activate both motor systems together for almost 300 horsepower
Even though, my wife absolutely fancies the Model X for those duties.
I don't like the optics of the Model X too much.
So maybe we have wait for the Model 3 (is there an 4 wheel drive option available?) as a possible replacement in a few years for my Vette and the Model Y for my wife.
