This is mostly true, but the cost of maintenance, fuel, and repair doesn't offset the cost insurance, electricity, and battery replacement for me over the course of 10 years, so my next vehicle will still be a petrol engine car unless something changes substantially. The big thing is, for me, an electric vehicle insurance quote for me ranges between 4K and 6K per year.
Yeah nobody is willing to give up the revenue/tax from someone driving a car. In fact, I bet electric vehicles will end up more expensive per mile, mark my words.
