Most homes only have enough 240V outlets for their clothes dryer and their A/C. It's an extra cost to have an electrician install an additional 240V circuit in the garage to charge the car overnight for decent local range.

You can also get an electrician to install a 480v transformer and wiring for about $3000 to $5000 depending on where you live and what capacity and quality transformer you get.
So gas at $3.00 a gallon would be 1000 gallons going with the cheaper transformer. Most modern cars about the size of EVs got at least 25mpg so there’s 25,000 miles of fuel. Not to mention electricity is not free, and most electric companies hit you with a monthly demand charge if you get your house set up to draw more than the standard residential capacity. So in really hot weather you can charge your car or run your air conditioning or pay the electric company more. BTW electric companies really love EVS I used to work for Ga Power and the more EVs people had the better they liked it.
