I think swappable batteries could be a good solution to fires and probelms seen with long term battery health. Like if batteries were smaller and you swap it out rather than charging they could be inspected before being redistributed. In an ideal situation the cost of purchasing a battery would be removed from the vehicle price and shift to a subscription/interchange system. It could help consumers if their battery goes bad by not needing to buy a completly new one and prevent fires. Unfortunately, everything is terrible and I imagine this would inevitably turn to some kind of scummy, overpriced, preditory system. I am not sure if damage caused by batteries is enough to justify such a program but I think insurance companies and governments have or will look into it.
