Hello. I live in WA and actually I'm wrong: 66% of our electricity is hydroelectric. And yes, of course everything in the world pretty much uses fossil fuels to be brought into existence. You can't count that, it applies to everything. The real question is the ongoing cost. Hydroelectric is about as green as it gets.

Sodium-ion batteries are not far away, and sodium is a plentiful resource that has one of the lowest costs to extract compared to minerals. (https://www.catl.com/en/news/665.html)

Public transport comes in many forms. When you consider that most urbanites in a city with well-developed public transport don't even own a car, it can work. E.g. London, NYT, Hong Kong, Singapore. When you bring in a decent high-speed rail network, you could argue cars are not necessary except for obscure destinations outside of the city. My point is you could reduce the world's car fleet by 75%.

I don't think the government argument is a valid one. You think they can't stop you using your car by road blocks everywhere, if they really wanted to? Or stopping the flow of gasoline? Which actually brings up another advantage of an EV :)
