When 52% of all trips made are less than 3 miles and less than 2% are over fifty miles, I don't think battery swapping is something any individual needs on a regular basis.
I could get on board if manufacturers were making $10,000 sub 50 mile vehicles that were compatible with a swap station so you could switch to a larger battery for the weekend. This would have to be a standard adopted by all however, and even before that, they'd have to make small cars. Which they won't, because we all know they are too busy making trucks and SUVs.
