Internal combustion engines in standard small size convert 19.65-22.1% of their energy from thermal to kinetic.
The ratio of electron throughput from battery to electric motor can be as LOW as 88% but hovers between 92-98% efficiency.
Even if you had a fuel cell in the back, running electric motors quintuples (5×) the standard energy efficiency owing to the principle of energy quality type preservation in conversion (High to High vs Low to High):
Jevon’s Paradox states that improved efficiency of something will only increase its use, and in this case, electric cars will in fact, correlate to car use, and increased mineral demands.
This is a problem you cannot solve endemic to humanity.
I think you missed the meaning of inefficency on this matter…
While it is undeniable that electric cars have a better supply-to-engine energy efficency than combustion cars, you can understand that they are equiparated in the meme as “equally bad” if you think outside of the box labelled “rubber wheels on high friction asphalt transporting usually a single individual”.
Compare that with a tram or a train, transporting multiple passengers with the same electric engine but also steel-on-steel friction on the wheels and the difference between an ICE and EV vehicle becomes a mere approximation error; god I can do the math for you if you want, but I bet even a disel bus with a lot of passengers has a better efficency/passenger ratio than an EV.
So 1 electric car = 4 less carbon liquid fuelled cars worth of pollution.
Also I think this is a bit misleading: if I buy an EV this won’t magically destroy 4 (where is this number from?) already existing carbon liquid cars, it merely means you avoided adding 1 other ICE car to the total.
Disagree on inefficient.

I think the point is that compared to public transport when transporting a large number of people, they are inefficient.
When is it efficient to carry several tons of steel with you to pick up eggs and milk?
