Re: Almost, but not quite.
Since my current car costs nearly £70 to fill up, the leasing cost doesn't look at all bad to me. Although I agree about it still costing you when it's not being used. That part might need some more thought. My 15 mile commute each way makes this look ideal even without a charging facility at the office.
And while I can see that cheap overnight electricity might disappear in the future I can also see the possibility of millions of plugged-in electric cars making up the shortfall for those world-cup-half-time moments when the whole country suddenly needs more power.
