I wonder how many people drive far enough to regularly need the range extender before they have a chance to plug it in. The fuel economy of this thing is not great if you drive it far enough that it runs out of petrol and you need to fill it up again - but what if you rarely do that? What if you usually drive less than about 50 miles before the next opportunity to recharge it?
