Better question is why are Deep States, plural, so keen on shoving them down their public’s throats..
When everyone is dependent on the electric grid, the grid can be shut down or choked to fix the proles in place.
It is about having power over the lives of others.
The goal is an immobilized peasantry that can travel only with permissions and instructions from the rulers.
The intermediate step is to "mandate" replacement of existing vehicles with ones that are more expensive and less capable. Then keep tightening the nooses by regulatory changes until ordinary people simply cannot afford or use any form of personal transportation.
Electric Vehicles are a "bait and switch".
I once overheard the well traveled mother of an employer say this:
We travel all over the world and have noticed that the workers in most other countries don't own a car or big house and they seem perfectly happy. Why can't our workers be like that?
There's a lot of people who don't think the workers deserve to drive or own a house. Factory workers and many blue collar types buy used cars because that's all they can afford. There will be no decent, affordable used EVs due to the short lifespan and replacement costs of the battery.
“Better question is why are Deep States, plural, so keen on shoving them down their public’s throats..”
They don’t. They want to outlaw private ownership of “fossil fuel” vehicles so they can control travel. So they outlaw gas cars and then price EV’s out of reach. Now citizens are forced to rely on the government for travel. Bring in a social credit system and you can punish people for opposing the elites.
The elites will still have gas vehicles and planes and you better approve.
