LOL. You must be living in a pretty happy plug in bubble. Which is great for you.
There are people living in apartment buildings, with no options to plug in anything. The best they've got is 110V and probably a talking to by building management if they plug in a car regularly without paying for the extra electricity that isn't billed to their own meter.
There are people who gasp work in buildings that don't have plug in infrastructure. We used to have a building that had posts to plug in hybrids and such, with a prioritized parking space, but we're not at that building anymore, and no one could use them anymore. They weren't 220V either, so it's more of a maintenance charge.
To get a 400 mile / 640km range, you're pretty much driving a Tesla. Not everyone could cough up the money, or even finance one that easily. And to charge up 400 mi on the mobile 110V on the NEMA 5-15 is a pathetic 133 hours. http://www.teslamotors.com/models-charging#/outlet
Or some of us live at places that has actual winters, where temperatures averages -20C, and can feel like worse than -40. Your charge drops like a stone in those situation, when you're out of that temperature ban. Not my words, this is from my friend who don't just own a plug in hybrid (which every weekend he has to find a free charging plug in the city to top up), but also a Li-ion battery engineer.
So yeah, you're right, a plug in electric car is a real car, if you're rich enough to at least finance it, rich enough to own a house to put in the wall charger, working in a good comfy job that has the luxury to consider green technology and weather that is basically never cold. i.e. Silicon Valley.
Some of us have friends that are 200km or 500km away. Last thing I'd want to do is to push a couple tons of metal and batteries out of the way on a highway.
Places like Detroit has coal fired plants.
