If by many north americans
If by many north americans you mean the minority of north americans then you are correct $440 is not affordable. If you mean the majority of north americans then you are wrong since when fuel and insurance and maintanence are considered the majority of north americans already spend more than $440 a month on a car (considering those that buy new). You could buy a cheap used vehicle but then they tend to be less fuel efficient and have higher maintanance costs. The batteries are typically warranteed for 7 years. If they are waranteed for 7 years that means they typically last longer than that. A 300 mile EV would waste 200 miles or more of battery every day. You would be hauling around a huge load of batteries that you pay to move and hardly ever use.
