Propane technology has matured and stabilised; a 2019 propane tank is no better than a 2009 propane tank, it'll be the same size, supply the same amount of energy, and have the same connectors. A 2029 propane tank will, in all likelihood, be the same.
The same cannot be said of EV battery technology.
So why the Tesla demo video? According to [1] just doing the demo entitled them to $90 million of Californian "ZEV credits", and they never believed in or planned to roll out the technology.

I wonder why it bothers people about battery packs, but not propane tanks. They seem to have equal chances of exploding.

What if some jerk replaces half his cells with rocks then swaps the pack and you get it?
You have to trust the charging station that you’re getting an equivalent pack in trade. Are incentives aligned to ensure that?
Gogoro has been quite successful with this model.
The difference, of course, is that a scooter takes batteries small enough to swap by hand.
The Gogoro model is really cool and I would love to see it expand to cars. I’m just providing an example of why people might object to the idea.
