I was thinking more along the lines of R&D on placement in the vehicles, not so much the battery tech itself. Meaning the current "Models" already have the current battery tech engineered into them for size, shape, weight, crash testing etc. So if you wanted to change them from X point down the road, I think it would be more advantageous to completely change the "Model " altogether and go from that point in time forward. I don't think it would be cost effective to try and retrofit this into current set ups.
