It's a well known fact that cars stay parked for over 90% of the time, so this idea has been floating around for a while. The wear and tear issue is only a concern if nothing changes in the way we currently charge for electricity, e.g. a fixed price that gets adjusted from time to time. But I don't think we will -- even today we have more and more providers that charge with prices fluctuating hourly to reflect wholesale market prices. Thus if you can charge dirt cheap and sell it later for a large multiple more, you have a big incentive to do that. With the rise of renewables that basically looks unstoppable this will become a reality a lot quicker than I think a lot of people anticipate.
