If you look at the efficiency from, say, coal burned in the power station to electricity in the batteries to driving, electric cars fare similar to internal combustion engines. (Burning your fuel in the big power station is more efficient than a car's internal combustion engine, but going through the extra steps of transmitting the energy to your home and then into the batteries eats some of that.)
And advances to generation technology increase the efficiency of everything downstream accordingly.
And perhaps most importantly: you avoid compromising a technology's best efficiency curve in the quest to meet the demands of the driving model.
e.g. even if you're burning fossil fuel to generate power, for whatever reason, there are vastly more-efficient ways to do it than the way we do in in-car ICEs. Those ways just happen to be ill-suited to the power-demands of personal vehicles.
Energy technology should ultimately improve our versatility. Putting batteries in a car doesn't achieve that goal just yet.
This all happens because there are a few folks who naively believe that batteries are a clean way to store energy.
You've gone from suggesting the batteries are insufficient to suggesting that correcting your misinformation and fear-mongering will itself raise the price of ICEs and their fuel.
You're burning down strawmen of your own imagining.
In any case full electric cars allow centralized power generation, in turn allowing more opportunities for clean power.
But, for 95% of trips, an overnight charge at 120V is sufficient.s
In theory. I can see at least a couple of challenges in making such a system feasible. It's not like you can just shove the batteries into a massive underground tank, for example.
An electric vehicle is more specialized as a every-day commuter vehicle. It is cheaper in that duty.
Like a gas car, your cell phone can do anything your desktop can do, but your desktop is better suited for some tasks (i.e. faster for writing letters) even if its mobility is less.
I remember when I was in the Army that our 5-ton dump trucks had lots of onboard stuff running off pressurized air, presumably making the vehicle more durable to electrical failures
Combine with local stored fossil fuels, and basic mobility/counter-mobility, and you have a harder-to-cripple ground force.
