>Not to mention that coal plants are way more efficient than ICE engine. The average efficiency at the wheel of a car is 18%
I'm not saying a coal power plant isn't more efficient but this is a one sided fanboy comparison if there ever was one.
What's the efficiency of the coal power plant after it's been used to charge up a battery and then discharged to power a car (i.e "at the wheel")? The fact that it's being used to drive a car around is the dominant term in the efficiency equation, not the form factor of the hydrocarbons. You did touch on supply chain but lithium batteries have some pretty nasty environmental impacts. I'm not sure whether they're better or worse than supplying liquid fuel.
