I don't think that will ever really be a thing. The problem with hot swap batteries is that you are trading a battery of unknown quality for something else.

Imagine swapping in a 10 yo battery for brand new battery. That would kind of suck.

The thing that will probably make things more tenable for non-home owners will be bigger battery densities. If you get 500 miles of range on a charge, then stopping by a fast charger once or twice a week wouldn't really be all that big of an issue. You don't even have to go to 100%, just enough to cover a week's worth of commuting.

The other thing that would make this better is a bigger source of public L2 or even L1 chargers.
