There are a few benefits with EV's. They work great for some people in some situations. I can see where they'd be a great thing for city commuters in warm weather.
The first problem comes when you force people to go to them in situations where they just don't work. Long commutes, cold weather, rural areas...
The second problem comes with the massive environmental pollution caused by the poisonous lithium batteries that need to be replaced every 5 to 7 years. Let alone the hazards of mining raw lithium (currently outsourced to third world countries because it's so toxic). We really need to place an environmental impact fee on the sale of every Li-Ion battery over a certain size and plan to use the proceeds to cover dead battery storage and clean-up from the inevitable disasters that are being created by them (toxic fires, land/water pollution, ect ect ect).
The third problem: since states can't collect road fund use taxes from the sale of gas and diesel, we need to find a way to collect road use tax from these EVs. A mileage tax, an ev charging station tax (even at home), or an extra tax every time the car needs a new set of tires due to wear...something. IDK.
