There's much more to it than what you stated. You have to consider what it takes to produce the electric car and what it's lifespan is, necessary repairs during that lifespan, etc. Carbon footprint.
My bet is the carbon footprint is about the same as manufacturing of gasoline vehicle.
I am biased toward electric cars because:
1.) They are fun to drive. As one of the Tesla tester described it. They have implant flattening acceleration.
2.) No oil changes EVER.
3.) Even when we buy the energy at retail they are still way cheaper to operate.
4.) Cost of "fuel" is way less volatile than gas or diesel.
5.) They are quiet.
6.) They reached a driving range that makes them practical transportation for majority of our driving (I mean like 99% even though we live 12 miles from the closest grocery store and 45 miles from large city)
7.) The Middle East can keep their oil. Screw them.
8.) The hydrocarbon saved can be used to make something more useful than heat.
9.) They can have, potentially, better aerodynamics. They have flat floor, no induced drag by air flow through engine compartment etc.
10.) They don't depend on single source of energy (crude oil) but can be powered by PV, wind, water, nuclear, coal, NG, bio fuels etc.
11.) We make our own electric power. That I would love to use for myself instead selling to the utility for $ 0.035/kWh.
12.) Charging time and instant availability is not too relevant for us. We are retired.
