Let's say that tesla and VW announce, next month; a new "Quick Swap Standard for Vehicle Batteries" and EV's suddenly become refillable at service stations. That would be a market mover in many senses.
Of course such a thing would be sane; so there's no chance of anything like it happening.
Especially if it meant the batteries were themselves more easily serviceable. Making batteries less a part of a car and more like a durable good like a keg could have serious economies of scale.
Tesla already tried battery swapping. Technically it is possible but there are some logistical issues and it's not cost competitive with fast charging.
