Battery swap was a scam to
Battery swap was a scam to get more tax credits and Musk got away with it. From a practical perspective, the idea was pretty absurd. Transporting these gigantic units around the landscape and trying to predict where they would be needed most would be next to impossible. There aren't enough Tesla's out there to derive a reasonable data set to base the inventory needs on. One week a swap station might get a bunch of cars, the next maybe none at all.
I know I would be pissed if I went out of my way to get a swap and there were no batteries available. Not to mention do you really want a bunch of minimum wage idiots tinkering with the power plant under your $70,000 car? What happens when they screw up and the car doesn't start? Gassing up an IC car is available anywhere, it is quick and it is easy. EV's can't match that.
