While I agree with you David, I don't think this is the case just with tiny cells. I do not see this being overcome with any kind of cells. The battery pack in an EV is the equivalent to the gas tank in an ICEV. How much do you suppose it costs to stamp out a gas tank. There is no way that a battery pack will ever be that cheap no matter what battery technology comes along, so the cost of the battery pack has to be made up for some place else in the car. I do think that other components have the potential to cost less or be totally eliminated, but I'm not sure there will ever be enough cost saving to make up for the huge difference between the cost of a battery pack versus the cost of a gas tank. In my opinion you will always be able to make an equivalent ICEV cheaper than an EV. Even our old EV standby arguments about maintenance and longevity don't hold up as well as they used to, as ICEV have improved dramatically in this area as well. I do think it is fun to think that we could probably take a trip to the moon today with a fresh set of batteries and fire the old moon rover right back up though :) No way an ICEV would ever last that long in that harsh of an environment ignoring the fact that one would have never run on the moon in the first place of course.
