Yes, that's a good point. But: the grid can be expanded and probably will be expanded. I don't have a BEV but I've run the numbers and it would work very well for me today, it's just that I have an old, non-connected and fairly recently rebuilt car that I'll drive into the ground. But if I were younger and still in the market for a new vehicle I would definitely consider an electric one, though I'd make sure it had LiFePO4 or maybe even LTO in it (not yet available). Battery tech is getting better rapidly now that sufficient funds is pumped into it and I would expect the next two generations to be major improvements over what's on the market today.
