Certainly the companies who are developing EVs with quick-change battery packs will need to worry about quick-theft. Stealing the battery from a current EV would require thieves to tow or drive the whole car to their chop-shop.I have a feeling that batteries will one day be theft targets.
Valuable materials, a second hand market for working batteries (if there is one for airbags there will be one for batteries).
Of course there could be some instant justice for the ones who mess up while doing it as they’re (A) heavy and (B) likely to catch fire…
