The problem here is that you think the only viable method to charge an electric vehicle is a level 2 or above charger. The average person, even in more rural areas, generally drives less than 60 miles in a day. Which is something that can be recouped overnight with a standard 15 amp outlet. And that's assuming it's only plugged in for 8 hours. Most people's cars sit idle at home much longer than that. You don't even need to go Fancy with a dryer Outlet much less a level2 charger.

Unless you're somewhat remote area is over 200 mi from the nearest charger the majority of electric vehicles will get you there without you having to drive like a grandma. As many of them have somewhere on the order of 250 to 280 miles of range on a full charge now.
