Since Gen III vehicles will be on a smaller chassis than the Model S and X, with (presumably) smaller battery packs, does that mean they will be incompatible with the planned battery swapping stations? Since the Model E is being positioned as a cheaper alternative to the Model S, is it possible that Tesla wouldn't retool the stations to be compatible with the batteries found in Gen III vehicles, citing the likelihood of its target audience opting for free supercharging over relatively expensive pack swaps?
