Meanwhile, I spend >half of my time in my i3 at its 94mph top speed limiter
If you charge at home, the topic of this thread, there’s no reason I can see to not be as inefficient as you want. It costs me <$2 to charge from 0% (obviously never the actual starting point) to full, and charging at home means I spend zero time on it (more convenient than ICE).
But, yeah, the above is why I said I wouldn’t own one if I couldn’t charge at home.
