This isn't really a story about electric vehicles as much as it is about an energy crisis. They could ban gasoline powered vehicles if they needed to reserve gas for power plants and generators if they really were strapped for energy.
Its only an emergency proposal so they can be ready for crisis in the coming winter.
A ban on electric cars is not the precaution they're taking. Building could use less power, offices and shops could close two hours earlier. Electric cars would not be banned according to reports, it usage will just be limited to essential things like going to your place of work, visiting the doctor, attending court appointment and more. They're not doing this because the cars consume too much energy, they're are doing this because they're facing an energy crises due to the war. Even the countries they import electricity from (France, Germany) are all facing electricity crisis.
Of course they wouldn't ban EV's. No one is disputing that. The concern is the government telling people they don't have the right to travel because of their own energy policy. If they wanted cheap energy, they have the ability to source it. Energy is the holds civil society together. Without it, things begin to unravel very quickly.
