I basically can't own a Tesla (even though I would like to!) as I would never be able to charge it.
EDIT: The electrical nerd in me had to see if someone has done this before, and yes, it would look like this: http://www.teslamotorsclub.com/showthread.php/19974-NEMA-14-...
NEMA-14-50 is the kind of outlet used by RVs and Campers, so putting one outside is pretty much a solved problem.
Though as other commenter have mentioned, actually getting a parking space outside your house may be the biggest challenge!
What's the solution to this? Maybe municipal EV charging networks or people charging their cars while they're at work during the day? And if you have a charger at work, trying not to drive too far over the weekend until charging stations become more widespread?
Also, there may not be any available even then. Certain areas in europe, in particular, are not architected for vehicle co-habitation with residential real estate in urban centers. So, by all means you can own a Tesla for your country home. But it may be rather impractical for your town-house. Even in NYC, its quite normal for people who own cars to keep them garaged off-stite. Athough, presumably, this is less of an issue as over time professional parking storage businesses could make a nice secondary income stream by charging a "convenience fee" to Tesla owners. Maybe 100 to 200 a month, maybe a whole lot more more. This type of fee is what they charge currently for a Range Rover or other SUV.
With batteries being the constraining cost I do not see how they are going to have a low end car with any real range beyond 100 or so. I just don't see the math.
I am seeing Leafs popping up all over, they may have hit their price threshold for that to occur in my area (US). It fits the commute profile of a large number of people, I would suspect that is true for those here.
