EVs are just marketing, they not much more efficient than gas cars, it just moves the energy source from fossil fuels to...well, nuclear at best, or centralized fossil fuel generators at worst. You are not fixing global warming with EV cars.
A small, dirty, gas moped is way more efficient, cheaper and green than the greenest EV car.
The real revolution is electric bicycles, unsurprisingly one of the most popular means of transportation in China. I saw an excellent graph that I can't find at the moment, which shows that a human on a bicycle is 10 times more efficient than the most efficient biological locomotion known (that of fish).
